Guest Star ???? Star Allies Go!

"Go on a friend adventure! Guest Star ??? Star Allies Go! is now unlocked!"

- Guest Star unlocked

'''Guest Star ???? Star Allies Go! (sometimes shortened as Guest Star ????' ) is a sub-game that appears in Kirby Star Allies.'' This sub-game acts as the Extra Mode, like Dededetour or Meta Knightmare Returns, but the player is a friend, similarly to Helper to Hero.

Gameplay
In this mode, the player plays as one of the game's friends and tries to traverse through the five worlds of the game as quickly as possible. The levels are almost identical to those from the story mode; however, some aspects vary:
 * All 1UPs, most food, and most Picture Pieces are replaced with Point Stars. Maxim Tomatoes become standard food items.
 * There are additional Room Guarders dispersed throughout the stages, which typically reward Power-Up Hearts.
 * Certain round-trip doors are inaccessible, being replaced with a collectible.
 * Some rooms only appear for specific Friends, generally tied to their abilities.
 * Some rooms are removed altogether, including all Friend Star sequences.
 * Some Dream Friends experience additional, unique rooms not seen outside of the Guest Star game.
 * There is a unique final boss, Morpho Knight, fought after Hyness instead of Void Termina.

Instead of rare Picture Pieces, players may collect Power-Up Hearts to increase their attack, speed, and health stats. Starting stats, especially health, are lower than base stats in Story Mode, so earning Power-Up Hearts is important for a successful attempt. In this sub-game, all point stars are heart-shaped rather than star-shaped, as they usually are.

Pressing a Big Switch causes collectibles to spawn, some of which may spawn a Dream Rod (one in Donut Dome for every friend; a second one in Friendly Field if the player uses Sir Kibble, Broom Hatter, or Birdon; and a third one on Planet Earthfall if the player uses a friend capable of doing a Friend Throw, such as Knuckle Joe and Gooey), allowing one to summon a Dream Friend. One must complete this mode as one of the standard friends (e.g. Blade Knight, Burning Leo) in order to unlock the ability to play this mode as a Dream Friend instead.

There are five levels, and at the end and midpoint of each level, the player can use a checkpoint to save and return to the title screen of this mode; these checkpoints also fully restore the health of each player. As in story mode, King Dedede and Meta Knight can be made Friends by throwing a Friend Heart at them after their defeat.

If amiibo is used at all during the playthrough, an amiibo insignia will appear next to the player's clear time. Similarily, the game will show if the playthrough was done with two players or more by showing the player number symbols next to the time for each level (P1, P2, P3 and P4).

Changes with Dream Friends
After Update 2.0.0 and 3.0.0, changes were made to the Guest Star mode that mainly relate to the Wave 1 and 2 Dream Friends:
 * When reaching the final boss rush (consisting of Zan Partizanne, Hyness, and Morpho Knight) while playing as certain Dream Friends, the arena will be slightly different than the one used in the main story and post-story content. In The Ultimate Choice, this only occurs during Morpho Knight's fight. Despite these changes, the gameplay of the boss rush itself remains the same. Divine_Terminus_Sunset.jpg
 * When playing as the Wave 1 Dream Friends in version 2.0.0, the dark, interstellar background is replaced with a cloudy sky at what appears to be sunset. The background architecture of The Divine Terminus has been flipped upside down, and pieces of it can be seen falling throughout the boss rush. The flowers, vines, and crystalline protrusions in the background have grown, and the buds of the flowers glow bright blue. A pool in the center of the arena resembles Hyper Zone, glowing with a light-blue aura.
 * When playing as the Wave 1 or Wave 2 Dream Friends in version 3.0.0, the arena is further altered. The upside-down Divine Terminus continues to deteriorate, and the boss arena itself has also begun to crumble. The flowers have grown even larger and now glow bright purple. Purplish vines hang above the arena, and the previously red crystalline protrusions have grown and now glow purple. The pool in the center is larger and now resembles the blood-red core of Dark Star, where Zero2 was fought.
 * The music in Morpho Knight's boss fight also changes under these conditions. When playing as Rick & Kine & Coo, the music is replaced by a remix of Dark Matter's boss theme and Cloudy Park. When playing as Marx, the music is an orchestral version of Marx's boss theme. When playing as Gooey, a remix of Hyper Zone's first theme plays. When playing as Adeleine and Ribbon, a mix of Zero2's theme, Miracle Matter's theme, and Ripple Star's stage select screen theme plays. When playing as Dark Meta Knight, a mix of the boss theme from Kirby & The Amazing Mirror and Dark Mind's theme plays. When playing as Daroach, a remix of the Squeaks' theme plays.
 * When playing as the Wave 1 Dream Friends, new areas appear at the beginning of Level 1, mid-way through Level 2, the beginning of Level 3, mid-way through Level 4, and the end of Level 5. The new areas in Levels 1, 3, and 5 reference other games in the series, and are different for each Dream Friend;
 * When playing as Rick & Kine & Coo, the new levels reference Stage 1 of Grass Land, Stage 1 of Red Canyon, and Stages 1 and 7 of Dark Castle from Kirby's Dream Land 2.
 * When playing as Marx, the new levels reference Green Greens, Peanut Plains, and Halfmoon from Kirby Super Star.
 * When playing as Gooey, the new levels reference Stage 1 of Grass Land, Stage 1 of Sand Canyon, and Stages 5 and 6 of Iceberg from Kirby's Dream Land 3.
 * When playing as any of the Wave 1 Dream Friends, Nature's Navel in Stage 2 and Planet Caverna in Stage 4 receive new original layouts. They do not reference any game in particular and are the same across all Wave 1 Dream Friends.
 * When playing as the Wave 2 Dream Friends, new areas appear at the beginning of Level 1, the beginning of Level 2, mid-way through Level 3, the beginning of Level 4, and the end of Level 5. Levels 1, 3, and 5 reference other games in the series, and are different for each Dream Friend.
 * When playing as Adeleine & Ribbon, the new levels reference Stage 1 of Pop Star, Stage 2 of Rock Star, and Stage 4 of Shiver Star.
 * When playing as Dark Meta Knight, the stages reference Rainbow Route, Moonlight Mansion, Carrot Castle, and Candy Constellation.
 * When playing as Daroach, the new levels reference Stage 1 of Prism Plains, Stage 1 of Vocal Volcano, and Stages 1, 2, 3, and 4 of Gamble Galaxy from Kirby: Squeak Squad.
 * When playing as any of the Wave 2 Dream Friends, Friendly Field in Stage 2 and Planet Earthfall in Stage 4 receive new original layouts. They do not reference any game in particular and are the same across all Wave 2 Dream Friends.
 * Before version 3.0.0, most characters had to go through the initial area of Extra Planet δ after Stage 5's first checkpoint. However, after the update, only the additional Dream Friends play through that area.
 * There are rooms resembling HAL Rooms, typically near the end of Guest Star, that contain blocks which spell out the names of Dream Friends added post-launch. Gooey's room plays the Ripple Field stage select theme from Kirby's Dream Land 3, Marx's room plays the title screen theme of Milky Way Wishes, and Rick & Kine & Coo's room plays the title screen theme from Kirby's Dream Land 2.
 * When playing as the Wave 2 Dream Friends, Adeleine's room plays the theme used for Stage 1 of Planet Popstar in Kirby 64: The Crystal Shards, Daroach's room plays the main menu theme from Kirby: Squeak Squad, and Dark Meta Knight's room plays the theme used in Central Circle, which also plays in the Collection Room and the game's intro.
 * At the end of every Dream Friend's curtain call, a unique picture will appear in the right-hand corner, showcasing a screenshot of them from the game they first appeared in.
 * However, Bandana Waddle Dee's unique picture is from Kirby Super Star Ultra, even though the first game he appeared was Kirby Super Star. This could be because Kirby Super Star Ultra was the first game to acknowledge him as a unique character, and his role grew in subsequent games.

Trivia

 * In Level 5, the player's character falls through several rooms containing Room Guarders before moving right to a room with another Room Guarder. The Room Guarder here is based on the player's character. For example, Blade Knight must fight several Blade Knights and Chef Kawasaki must fight Twin Kawasaki.
 * When the player chooses a character, the name of the mode changes. The "????" is replaced with the name of the chosen character and "Star Allies Go!" is replaced with a unique phrase for each character.
 * Before the 3.0.0 update, through a glitch, it is possible to play as Kirby in this mode. To do this, one must have the Nintendo Switch in Handheld or Tabletop mode, and then tap between New Game and Best Times. If the right place is tapped, the mode will start as Kirby. However, Kirby does not have any flavor text (the text is in Japanese that means “No Data Set”).
 * The credits theme for beating Guest Star mode is a remix of the credit themes from Kirby's Dream Land, Kirby's Adventure, and Kirby Super Star.
 * Gim's special quote implies that he was unaware that the events of Kirby: Planet Robobot have already been resolved. Alternatively, it could suggest that Kirby Star Allies takes place before the events of that game but Gim still somehow knows of the Haltmann Works Company and its ambitions.
 * Gim's special quote also erroneously reads "With word of a mechanized invasion in the the works...".
 * Prior to the 2.0.0 update, King Dedede, Meta Knight and Bandana Waddle Dee did not have their own unique intro menus and instead shared the standard intro menu that all the other friends shared.
 * In the 3.0.0 Update, Guest Star now allows the player to have multiple save files for each friend, and if the player has played the mode before the update, they can continue by creating a save file through the Best Times records. In the update, stages for the regular Friends have been upgraded as well.
