The series follows two anthropomorphic animals, Ed and Buddy, a dog and a squirrel respectively, who live in the town of Swellville in the north of the United States. Their adventures and sometimes mis-adventures usually cause them to interact with other characters. While Ed is well-liked by all, and extremely lucky, Buddy is vehemently despised, and extremely unlucky, gratuitously so.
Characters
Main
Ed – A yellow dog. Ed is overenthusiastic and helpful, but rather dimwitted. He has many catchphrases, such as his trademark 'Yee!' and 'I'm here to help!', as well as 'Sacagawea!', 'Krakatoa!' and 'Well isn't that curious?' He has a speech impediment which makes him often say 'sh' rather than 's'. He has 'happy sandals', and is a frequent viewer of The Mighty Measel Moles, a Star Trek parody, both of which Buddy hates. He has numerous skills. Much focus is drawn to his navel. He is well liked by everyone in the neighborhood, although he considers Buddy his best friend. Buddy AKA Doug – An orange squirrel. Buddy is more level-headed and intelligent than Ed. He suffers incredibly from the antics of Ed, and everyone else, and only ends the episode happily in only a few episodes. He still does consider himself good friends with Ed. Everyone else dislikes him. He enjoys nuts, and has a car with a giant acorn for a roof. He was part of a club devoted to the nerdy role playing gameBattle Buddies awhile ago. His catchphrases are "Oh no, please, no!" and 'It's Doug, actually'.
