This week's episode it EGGHEADS
This episode is about Eggman baking a bunch of evil cookies in an attempt to trick Sonic to eat them. However, much to the good doctor's irritation, the cookies ended up being eaten by everyone EXCEPT Sonic. This causes Sonic's friends to turn evil and now Sonic has to save them.
This episode actually had some pretty good laughs. The entire concept of evil cookies is ridiculous, but this episode does find a way to make it funny. That awkward bit with Sonic and Knuckles is a good example. That and seeing Tails, Knuckles, Amy and Sticks being evil. The end fight, however, is priceless.
I give this one a 4/5
