- "What time is it?"
- ―Jake the Dog
Jake can morph into all sorts of fantastic shapes with his powers, but typically takes the form of an average sized yellow-orange bulldog.
Jake loves to eat. He likes junk food, especially pie, burgers, and ice cream. Jake is generally laid-back and tends not to worry about things. He relies heavily on his powers (or Finn) to get him out of any dangerous predicament. While he often cracks jokes at serious times, Jake always has a lecture or a song to cheer Finn up if he is feeling disheartened. Acting as Finn's world-wise mentor, Jake is always willing to give input and advice about a situation, but his suggestions are usually inconsistent, ranging from encouraging and helpful suggestions to ridiculous nonsense. He can be somewhat irresponsible at times, frequently leaving Finn to fight most of a battle on his own, but he always pulls through when he is needed most.
