Charold is a character found in the Underwhere in The Flip Flop Show. For a fee of four coins, he will ferry the Bleu across the River Twygz. However, this is not required, since the four heroes can just swim across the water. The relation between Charold and Muffy is not mentioned. It's also unknown whether or not Charold is, in fact, living his "after-game" life or working for Muffy. Charold's name is a portmentau of the ferrier of the Underworld in Greek Mythology, Charon, and the name Harold.
