Paxton (voiced by Jason Marsden) is a (formerly) pessimistic parrot owned by Mr. Barker.
Paxton always looked on the bad side of things. After escaping from Jon's house (where he was once being supervised), he spread his doom and gloom point of view around the city. He finally stopped after Odie licked him, which he saw as the first sign of affection towards him. He later hosted a TV show where he talked about being happy.
