I wonder, did the P5S writing team base Zenkichi off P4's Dojima? Their backstories are strikingly (heh) similar, too much so to be mere coincidence...
Akira, my other favorite episode of Sesame Street is when Zoey wants Telly to take care of her pet rock, Rocco, while she’s away. This episode includes the episode of Elmo’s world about babies. Because they’re so cute and adorable.
