Caboose seems to act very childish as his understanding of the world and actions are incorrect and shows a great amount of curiosity. However, Caboose does show a lot of care to many characters, even to the Reds, despite them being rivals. He often tries to impress others in order to gain their respect, although it often backfires in some way. Caboose shows a great amount of loyalty as well, as shown when he kept trying to resurrect his best friend, Leonard L. Church.
