Omochao

Omochao is a robotic Chao that serves as the tutorial guide in some Sonic games. He annoys Sonic in SMG4's bloopers, similar to Tails.

Omochao's first (and so far only) appearance in SMG4's bloopers is in Sonic the derphog: Eggventure (GET IT!?), where he wakes up Sonic in the beginning and tells him he has to save the world, but not before getting shot by Sonic. He later appears at the very end, telling Sonic he saved the world, before Dr. Robotnik the Teletubby appears and says "The End".
