Pierron

Pierron is a demon-like green and yellow creature. It has bat wings, horns, and fists.

Grow v.1
Pierron hatches from the egg if exposed to moonlight. Hitting it with a Piko Piko Hammer will result in an Onky popping out. Gluing it back together will make it monochrome. The Onky will then hop on and ride it in the air.

Grow Tower
After the Living Rock Creature is sucked into the machine, it will be processed into a Pierron. The demon then flies again until it is again swallowed by the pot. After the pot upgrades into a cannon, the Pierron is launched into a panel. When the Pierron is used, it is hit with a Piko Piko Hammer and an Onky pops out (similar to Grow v.1) and pulls the sun cord.
