At some point there happens to be a Thing Three and Thing Four if the Cat ever needs extra help.
In the film, Thing One is played Danielle Chuchran and Taylor Rice, and Thing Two was played by Brittany Oaks and Talia-Lynn Prairie but Dan Castellaneta provided the voices for both of the two Things. In the deleted scenes of this film, the Things stop Joan Walden by three methods of a flood.
In The Cat in the Hat (1971 cartoon), Thing 1 was voiced by Thurl Ravenscroft and Thing 2 was voiced by Lewis Morford.
The Things wear red jumpsuits with the logos 1 and 2, and they have blue afro hair in their other appearances. In the Learning Library, they are wearing blue jumpsuits and their afro hair is blonde.
