Jake the Dog is a fictional character in the American animated television series Adventure Time created by Pendleton Ward. He can stretch, shrink, or mold any part of his body to any shape and almost any size, ranging from becoming gigantic to becoming incredibly small. He acts as a confident mentor to his energetic adopted brother Finn, though has a tendency to give somewhat questionable advice. Jake has a laid-back attitude in most situations, but loves adventure and will eagerly fight when he needs to. His powers help Finn considerably in combat and transportation, but are also sometimes used as nothing more than jovial forms of expression. He has a partner named Lady Rainicorn ; they have five children together as seen in "Jake the Dad". He is quite skilled at playing the viola, which houses a worm called Shelby.
