He is taller than the other bears of his tribe and is the only one who wears clothing and shoes. He has brown fur, moderately big ears, and brown hair, and he wears a grey-ish green fedora with a red band and a piece of yellow paper sticking out, an olive green jacket with darker olive green elbow patches, a yellow inner collared shirt, grey-ish blue pants, and black shoes, along with a dark grey handbag. Pat is much more human-like than the other bears. It's unknown if he is just a special, mutated bear or a member of a different species entirely.
For the leader of the party bears, Party Pat is surprisingly calm and stoic. He generally sports a blank, unresponsive expression, as if he is deep in thought. He speaks in a calm, decisive manner, giving him something of an air of wisdom, though this may just be a front. Despite his sophisticated manner of speaking, he is not above jovial pranking. He treats partying as a spiritual practice and a way of life rather than just something one does for fun, and he takes partying very seriously. As a result, Party Pat holds partying above all other things, including the safety of himself and his people.

See Party Pat/Quotes
- Party Pat's appearance is based on Adventure Time creative director Patrick McHale. This is the second character created based on Pat; the others are Gingerbread Pat and Punsy McKale, a character in The Marvelous Misadventures of Flapjack.
- At a point in "Belly of the Beast," Party Pat appears to be wearing shoes in one frame, and then barefoot in the next. This occurs near the end of the episode when he is standing next to Finn and Jake outside the monster. This could just be a mistake on the animators' part.
- Party Pat appears in issue 4 of the Adventure Time comics.
- He is the first of the two bears in the series named Pat, the second being Kim Kil Wan's wife.
