The Toonzai dub should have just never been a thing. Kai was successful enough on Nicktoons; there was no reason to release a dumbed-down version of the dub on another channel for extra ratings. Blue Popo was an embarassment.
All I know is Mr Popo was blue and Chazou exploded into a pink candy floss cloud...which might actually be worse because where did the pink colour come from...blood. SCARY.
