Theodore is the very indecisive one. He always thinks a lot, stutters, cannot make a decision, and then he says something random. For example, "Mrs Mung-uh I would-uh, I would like-um, to go-uh, no, I-uh. Shoes?" He is voiced by Peter Hastings, also the voice of Mrs. Munger.
The photo used for Theodore is of Theodore Falce, whose photo was also used for Grace.
