Bubbles is a rare enemy in the Kirby series that resembles a blue smiling ball. They tend to bounce around the place gleefully. If Kirby eats one he can get the Ball ability. Bubbles has only appeared in Kirby's Adventure and the remake, Kirby: Nightmare in Dreamland. In Kirby: Nightmare in Dreamland, it appears to have blushed cheeks.
They bounce all over the place, normally switching directions whenever they hit a vertical surface. However, at times they seem to be trying to hit Kirby, and in these cases they can be hard to get rid of.
