Kingdom Hearts 2 Episode 5 -The Adventures of Pete and Pete

We got a short trip to the distant past in this episode! Bad stuff is going down in Disney Castle so it's up to Sora, Donald, and Goofy to enlist the help of a possibly evil wizard to break the rules of time and space so that they can return to King Mickey's roots and save the cornerstone! Lots of Pete antics on the plate today, double the Pete, in fact! So much Pete you can hardly believe your Petes! Wait... just what the hell shape is a cornerstone?
