|“||I'd suggest making a note of which doors you go through as you explore.”|
|— Daroach • Kirby Mass Attack|
Doors are portals that allow Kirby to move from one area to another. In most cases, they are black arches with stars along the top. In Kirby's Adventure, doors do not have any stars around them except for the final door in each level.
In Kirby & The Amazing Mirror, they are replaced by mirrors, which act exactly like a regular door, but can sometimes lead Kirby to different worlds. An enemy, Mirra, is sometimes seen latched onto a mirror, and must be defeated before Kirby can enter. Sometimes, both types of doors are hidden by Star Blocks, and other times Kirby needs to pound a stake to break down walls and reveal doors.
In Kirby: Canvas Curse, doors are slightly bigger relative to Kirby and have more stars. The final door is replaced by a rainbow canvas that warps Kirby out of the dimension upon contact. A door is also drawn in Paint Panic.
In most games, the player must press up to enter a door. In all touch screen-based games (Kirby: Canvas Curse, Kirby Mass Attack, and Kirby and the Rainbow Curse), Kirby enters the door by touching it.
Usually, certain doors look different than others in the same game, which often denotes a different type of area. In Kirby's Return to Dream Land onward, doors with orange stars above them, called round-trip doors, lead to secret rooms or even different routes that contain more bonuses than the regular path. Doors simply leading through the levels have the traditional yellow star. Additionally, the final door in each level that serves as its exit looks different; it has a golden arch and a star on top with wings. Kirby can carry items, like keys, through doors.
In Kirby: Planet Robobot, larger doors exist to accommodate Robobot Armor, which cannot fit through normal doors. Some large doors are closed with roll gates, preventing Kirby from entering without the Armor. Roll gate-covered doors do not appear in stages that require use of the Jet and Wheel Modes, as Jet Mode skips doors altogether and Wheel Mode lacks the arms needed to lift roll gates.
The Moon is a reoccurring secret area appearing in Kirby games. It usually appears as a crescent moon high in the night sky, but is sometimes replaced with a different celestial object, such as a star.
So far, it has appeared in Kirby's Dream Land, Kirby's Adventure, Kirby Super Star, Kirby: Nightmare in Dream Land, Kirby Super Star Ultra, Kirby's Return to Dream Land, Kirby: Triple Deluxe, and Kirby: Planet Robobot. Most of the time, it is a simple Easter egg. In some games, however, it is mandatory to achieve 100%.
The moon makes its first appearance in the Bubbly Clouds stage of Kirby's Dream Land. After entering the moon, Kirby is falling, along with three Maxim Tomatoes and two 1UPs. It's not possible to collect all of the items, however. At the very bottom is a door leading to Kracko.
Stage 6 of Rainbow Resort is a homage of Kirby's Dream Land. One of the segments is from Bubbly Clouds. This segment still has the moon, in which, upon being entered, leads Kirby to the last Switch, as well as supplying him with a Maxim Tomato and a 1UP. The moon in the Extra Mode and Meta Knightmare remains unchanged.
Spring Breeze is a Sub-game based off of Kirby's Dream Land. Bubbly Clouds is still a stage and the moon can still be entered; just watch out for the falling Grizzo. Kirby will fall as usual, but there are no Maxim Tomatoes, but food scattered everywhere. There are four clusters of grapes, five pieces of meat, four peaches, and a 1UP at the far right. At the bottom is the door leading to Kracko, but Kirby will also come across a Noddy and Bonkers, which the player may choose to fight. Should the player float out of view of of the Noddy and Bonkers, they will respawn. The moon in Meta Knightmare Ultra remains unchanged.
In Kirby Super Star Ultra, the moon also appears in the new sub-game, Revenge of the King. Here it appears in Crash Clouds. The grapes are replaced with bananas, the meat is replaced with soda, and the peaches are replaced with meat. The locations of the food and 1UP remain the same, however. At the bottom is another Noddy and another Mid-boss, Grand Wheelie. This fight is not optional if Kirby enters the moon. Upon defeating Grand Wheelie, Kirby may then proceed to exit and fight Kracko's Revenge. Floating out of view of Noddy and Grand Wheelie will not cause Grand Wheelie to respawn, but Noddy will respawn like most enemies.
In Stage 3 of Dangerous Dinner, Kirby should ride the Warp Star to the exit door, but instead of entering the door, float above it to the planetoid in the background. Kirby can enter this planetoid like the moon. Kirby will spawn on a platform. He can fall from the platform and collect up to 100 Stars, a pair of cherries, a cake, an ice cream cone, meat, a Maxim Tomato, and a 1UP. Two Pop Flowers also appear at the bottom.
The moon makes its appearance in Royal Road. In Stage 1 of Royal Road, Kirby will fight against Gigant Edge in the wind. Upon defeating Gigant Edge, Kirby can skip the door that appeared and continue to the right. After floating up, Kirby can collect some items. In the background is the moon. Entering the moon will lead Kirby into the second HAL Room.
The moon also appears in Stage 8 of Royal Road. In the last room, Hypernova Kirby reveals a timeline showing his various appearances. At the very end, Kirby is found with King Dedede on Bubbly Clouds. To the left is the last Sun Stone representing the sun, and to the right is the moon. Kirby can skip the exit door again and enter the moon. Entering the moon will lead to a room of similar theme to Fine Fields, in which the Cookie Country music plays. Kirby may fall and collect the following: cherries, a pineapple, bananas, a peach, a watermelon, acorn squash, a carrot, lemonade, a cake, a cake slice, an ice cream cone, a sandwich, a red star, a doughnut, flan, a chocolate bar, omurice, another red star, curry, bread, a hamburger, pizza, meat, three 1UPs, a rare keychain (Taranza), two normal keychains, and two blue stars.
At the end of Stage 8 of Access Ark, Kirby makes an 8-bit hologram appear of himself and Meta Knight fighting; Bubbly Clouds is used as the backdrop. Kirby can enter the hologram's moon. He falls through an area in Fine Fields, where he collects food, stickers, and stars. At the end, if Kirby uses his Robobot Armor to unscrew a couple of screws near the door, he finds a huge one that makes him reach an upper platform. The Dream Hatcher sticker is hidden here.
