Gooey is a friendly blob of Dark Matter. He first appears in Kirby's Dream Land 2, where he is found in bags after defeating certain mid-bosses. He only appears when the animal friend that's found in the bag is already paired with Kirby when the bag is opened, and he replenishes Kirby's health. Gooey returns in Kirby's Dream Land 3, where he can be controlled by the CPU or by the second player. Gooey has similar powers to Kirby, except that he licks up enemies, instead of inhaling them. He can lick up stars, and can devour enemies underwater, while Kirby inhales stars, and often cannot eat underwater. However, unlike Kirby, Gooey can't eat two enemies at the same time. During the game's final battle in space, 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.
