Pacto

Pacto is a yellow, mouth-like enemy from Kirby's Dream Land 3 and Kirby: Canvas Curse. They are invincible in Kirby: Canvas Curse, because tapping them with the stylus does nothing, while they can be defeated in Kirby's Dream Land 3 with a Copy Ability. Pacto's name suggests that it may be based off Pac-Man, a famous video game hero.

In the sub-game Paint Panic, Paint Roller may have the player paint a Pacto.

Pacto also appears in Kirby's Return to Dream Land. It takes a few more successful hits to defeat than in the other games. In addition, a white version of Pacto appears in Nutty Noon.

Appearance
Pacto is a large, yellow creature. It has red, sharp teeth and a single eye with a small pupil. It attacks by hiding in a hole or open area and jumps out to eat Kirby. It also has what appears to be small legs. The enemy Maw from Kirby 64: The Crystal Shards heavily resembles Pacto, also having similar attack patterns.

Trivia

 * With the exception of the invincible Shotzo, Pacto and Dekabu are the only enemies in Kirby's Dream Land 3 to be instantly destroyed by the Ice ability. As larger foes, they would have required a larger ice block to encase them -- this is likely the reason they cannot be frozen.
