Paint is one of Kirby's copy abilities, first seen in Kirby Super Star. It is a rare, one-use ability that lets Kirby spray blobs of paint all over, causing damage to any foe on screen. As a side effect, the behavior of two certain bosses will be changed when this power is used against them.
Inhaling a paint ball from Marx Soul, Chameleo Arm, or Heavy Lobster gives this one-time ability. Performing the attack will destroy all regular enemies on-screen, re-color Chameleo Arm, re-color Heavy Lobster, and damage Heavy Lobster's eye, causing erratic movement. Chameleo Arm can still change color afterwards, however. The attack deals very little damage to Marx Soul.
In Kirby: Right Back at Ya!
Kirby has obtained Paint in just one episode of Kirby: Right Back at Ya!, after inhaling one of Paint Roller's paint brushes. Along with the ability's standard hat, it also came with a pair of roller skates, which could be a reference to Paint Roller himself. Like Cook before it, it became a normal ability rather than a one-use ability, and allowed him to paint things that became real. This is similar to the characters Ado and Adeleine.

In the transformation sequence, Kirby dons the skates of Paint Roller. Next, a similar blue hat falls on Kirby's head. After, he takes out the paintbrush and skates across the screen and paints the screen in multiple colors.
