Just a thought...

I noticed that a battleship casually joined the crew in both the opening and ending of Bobobo-bo Bo-bobo. It felt especially jarring in the ending. I guess I wasn't really paying that close attention back when it first aired. Anyway, about that... Didn't we never team up before? At most, you just created an entry route to the Dark Emperor's lair as a hidden talent, right? (And even that was something Bo-bobo did on his own.)
