Here is a screen shot from Billy Hatcher the game. Sonic Team members worked on it too, & Billy (the kid dressed like a chicken) rolled eggs to squash nightmare things & hatch the eggs into creatures to help you. But since it's an ST item as well, Sonic can show up. If you get enough coins, a "SonicTeam" logo egg will appear, & a Sonic will hatch out & use attacks like tornados & spins to do damage & help you. You could also hatch Samba De Amigo's "Amigo Monkey". The egg at right is the one that any of those characters could hatch out of. Added info by pr0w1.
