Old friends, Carrot Top and Berry Punch decided ti would be a good idea if they lived together and, mostly, it has been. Unfortunately for Carrot Top, though, she's now stuck with Berry's antics twenty four hours a day, and can already feel her sanity slipping away.
Derpy's habit of helping herself to a carrot every now and then isn't helping things at all, and the less said about Colgate's theories, the better.
