Well you certainly have piqued my interest.
Part of me is trying to think of what each member brings to the team.
Max brings his Monster-taming Stare.
The Cat in the Hat brings 26 "Little Cats" and a VOOM beneath his hat.
Mr Tickle has long arms and an innate sense of where a person's most ticklish spot is.
Oscar has a nearly infinite quantity of low-quality but strangely useful stuff in his surprisingly spacious can. (It's bigger on the inside. Is he a Time Lord in disguise?)
Scuffy the Tugboat is hard to gauge. Except for an irrepressible sense of exploration he doesn't bring a lot.
