Piko Piko (ピコピコ Pikopiko?) is an enemy that appears in Sonic Advance 2. It is a model of Badniks that are created by Dr. Eggman and appears in Music Plant (if the game difficulty is set to Normal).
It is modeled after a clown, and it wields a hammer that it constantly swings towards either side of him while moving to attack its enemies.
- The Piko Piko Hammer is a popular children's toy in Japan, named for the sound that it makes when it strikes something. The hammer wielded by Piko Piko is based on this toy, hence the Badnik's name.
- Amy Rose carries a weapon of the same variety.
