2140. Theodore Seville

Theodore Seville is the third and last born of the three chipmunks. He is the child of innocence and is shy, loving, gullible, naive, sensitive, and overall cute. Due to this, he is an easy target for Alvin's manipulations. In fact, Theodore often holds the swing vote between his brothers' choices of action. Simon appeals to Theodore's better nature while Alvin goes straight to bribery. He constantly is seen eating food and craving snacks.
Theodore's signature color is green and green eyes as well. He plays the drums. He is also the baby of the group and is deeply loved and cared by his elder brothers, especially by Alvin, but he refuses to admit it.
