I had been waiting a long time for this episode and when it premered I wasn't dissapointed.
I don't know what I like more seeing the gang as little kids, the fight against Nightmare, Bobobo's awesome fear of playing basketball with kangaroos, or the fusion of Bobobo and Don Patch into Bobobopatch (or at least a poorly drawn version of him.) And what was really funny was that even though he's poorly drawn he's incredibly powerful. I couldn't believe that energy dragon that he made.
I wish all the episodes were like this, but then again they are all funny in their weird way.
