Toot was the sidekick to Newton who, in turn, was the sidekick to Hercules in the old cartoon show of the latter's namesake. Toot couldn't speak, preferring to do his talking through his pipes...similar to the Pipes of Pan but for a good cause.
There was an episode where Owlman told Hercules that Toot was a lot wiser than he realized. Go figure...I always thought that Toot was insanely jealous of Herc because Newton kept fawning over him. How anyone could hang out with a prissy centaur like Newton is beyond me.
