|“||My name? Gooey? Maybe?”|
|— Gooey • Kirby Star Allies|
Gooey is simply a blue blob with round, googly eyes and a long, red tongue. His female counterpart seems to be pink with a big bow-tie on top of her head.
Gooey's personality is never thoroughly explored until Kirby Star Allies, where he is shown to be absent-minded, which somewhat lines up with his depiction in Kirby's Dream Land 3, where he is more focused on eating his fish than the Dark Matter invasion, and when Kirby and friends use him as a ball to play with, he has no objection. He is shown to be kind, such as when he tries to comfort Chuchu about her crushed flower, and potentially a deep thinker as he tries to "answer the questions of life" in Kirby Star Allies.
Gooey first appears in this game, where he is found in bags after defeating certain mid-bosses. He only appears when the Animal Friend supposed to be found in the bag is already paired with Kirby when it is opened, and he replenishes Kirby's health.
Rarely, a female version of Gooey will be produced from the sack instead of the usual male one. She gives Kirby a 1UP. The first time she is found, she adds 1% to the game's completion, making it necessary to find her in order to earn 100%.
Gooey can be controlled by the CPU or by a second player. Gooey has similar powers to Kirby, specifically, he can also absorb the enemies' powers, with the exception that he licks them up as opposed to inhaling them. He can also team up with any of the Animal Friends just like Kirby, giving him the same Copy Ability combinations. Gooey, as an advantage over Kirby, can lick up stars and devour enemies underwater; however, unlike Kirby, Gooey can't eat two enemies at the same time. During the game's final battle in the Hyper Zone, Gooey's flying form is similar to Dark Matter's appearance, but with a different color scheme and facial features. It costs Kirby one square (2 HP) out of five to summon Gooey.
Gooey makes an appearance as a Dream Friend in the game's first update. Gooey's attacks use moves from Whip, Burning, Parasol, and Stone, and he can use and give the Splash attribute with his tongue and Parasol, and the Sizzle attribute with Burning Gooey. He can use the Friend Throw ability and acts identically to Stone when having Curling, Geokinesis, and Rock Painter.
|Quick Lick||Press and release B||Gooey quickly shoots out his tongue, dealing damage and grabbing items. Can be used to grant the Splash element to allies.|
|Flicker Lick||B repeatedly||Gooey's tongue stays out after shooting it out, trapping enemies in the attack until the player stops pressing B.|
|Snack Lick||Press and hold B, and then release||Gooey's tongue grabs an enemy or star.|
|Tongue Slingshot||Snack lick + B/Snack Lick + →||Gooey throws the enemy/star, similar to the Suplex ability.|
|Parasol Gooey||↑ + B||Gooey summons a parasol and holds it above his head, dealing damage.|
|Parasol Spin||Press and hold B during Parasol Gooey||Gooey will spin his parasol around, causing enemies that touch it to go flying in the opposite direction.|
|Burning Gooey||Dash + B||Gooey bursts forward for a short time, creating a fire effect. This attack also gives allies the Sizzle element.|
|Stone Gooey||↓ + B||Gooey transforms into his Stone form from Kirby's Dream Land 3. It acts the exact same way as the normal Stone Copy Ability, although it does not change shape. However, when combined with the Splash, Blizzard, or Bluster elements, Gooey transforms into a curling stone, just like the standard Stone ability. He can also be combined with the Artist ability to create a giant painted statue of Gooey, or the ESP ability to trigger Geokinesis.|
|Dark Laser Flare||↓, and then ↑ + B||Gooey leaps up into the air, transforms into his Mock Matter form, and shoots four lasers in an X-formation.|
|Mock Matter||A in midair||Gooey transforms into a form very similar to that of Dark Matter. While in this form, Gooey can hover by pressing A, though he slowly loses altitude between presses.|
|Dark Laser||B during Mock Matter||Gooey shoots out a laser, which travels about halfway across the screen. Although it only shoots out of his front side, it will target any enemy that he is facing. Using this attack will cause Gooey to stop losing altitude while in his Mock Matter form.|
|Protective Bag||L/R||Gooey hides in a bag similar to the one he is trapped inside in Kirby's Dream Land 2. This works the exact same way as dodging, although Gooey cannot move while in this state.|
|Friend Grab||Hold ↑||Friends jump on Gooey's tongue.|
|Friend Throw||Press B/joystick after using Friend Grab||Gooey throws the friend he is currently throwing, much like the Suplex, Fighter, or Beetle ability. Holding the joystick in different directions before pressing B will change where the friend is thrown.|

|“||While Kirby swallows enemies in order to copy their powers, Gooey wraps them up in his tongue to steal their abilities. In Kirby's Dream Land 2, he occasionally appeared inside of a bag, but by Kirby's Dream Land 3, he was a full-fledged partner. He could be controlled by setting him up as Player Two.”|

|“||Gooey from Kirby's Dream Land 3 has hopped over for a visit. That oddball!”|
|— Gooey • Kirby Star Allies|
|“||This googly-eyed wonder from Kirby's Dream Land 3 comes in search of answers to the big questions in life... Who am I? Where? What time is it?”|
|— Guest Star description • Kirby Star Allies|
|“||It's Gooey-with the ridiculously long tongue! This weird wobbler has hopped in from Kirby's Dream Land 3. Not even Gooey knows why he's here, but we're all glad to see him show up!”|
|— Flavor Text • Kirby Star Allies|
- Gooey's use of his tongue to ingest enemies is similar to the abilities of Yoshi from the Mario series.
- The fact that Gooey is a friend of Kirby's proves that even a creature related to Dark Matter has free will and independent thought.
- In Kirby's Dream Land 3, the player is able to exploit a glitch to regain health. When Kirby has one hit point, he can summon Gooey and then swallow him to gain two more hit points, boosting his vitality to a total of three. Summoning Gooey again will take away the vitality gained, so Kirby cannot do this repeatedly to fully recover.
- In the Japanese version of Kirby's Dream Land 2, a character named Chao from the Japan-only game Yūyūki made a cameo appearance. Since the reference would understandably be lost on people overseas, she was replaced with the female variant of Gooey. Despite this, however, Chao herself later appears in all releases of Kirby's Dream Land 3 along with Goku, another character from the same game.
- Although no arms are seen during most of his moves, when holding the parasol after getting its ability, a single stubby arm can be seen sprouting out of Gooey's body.
- This seems to have been retconned in Kirby Star Allies since he now uses his tongue to hold the parasol.
- When Gooey uses the Burning ability, the color of the fire is blue, due to the nature of Gooey's transformations.
- In Ado's depiction of Gooey, he appears to have a forked tongue, despite appearing with a normal tongue.
- When using Rock Painter, Gooey's stone form references the opening of Kirby's Dream Land 3, where Gooey holds a fish with his tongue.
- In Guest Star ???? Star Allies Go!, when Gooey faces Morpho Knight, a remix of the first Hyper Zone theme from Kirby's Dream Land 3 plays instead of the normal theme, perhaps referencing Gooey's connection to Dark Matter.
- Though not stated in his move set in Kirby Star Allies, Gooey is capable of doing the Searing Burn move like Fire Kirby.
- Kirby Star Allies erroneously states that Gooey first appeared in Kirby's Dream Land 3 when he actually first appeared in Kirby's Dream Land 2. However, it could be due to the fact that Gooey was a playable character in Kirby's Dream Land 3, whereas his appearance in Kirby's Dream Land 2 only served a minor role.
