Jake

Jake the Dog:

Jake is the confidante, the dependable buddy, the designated driver when Finn gets all tuckered out. He’s the crutch when Finn falls, the guiding hand to pick him back up; Jake is Finn’s best friend. Like a cool older sibling (Jake’s 28 in dog years) Finn can always turn to him for advice about confusing stuff, like emotions and girls. His reassuring presence lets Finn feel free to act like a goofball. Jake also has magical stretching powers!

Jake's Stretchy Powers enable him to modify the size, shape, and dimensions of every part of his body. Not only can he stretch and contort himself into highly specific forms, but he can also rearrange his internal organs, and teeth. In "Evicted!" he was able to shrink and move his internal organs and blood into his left thumb. Also in "Jake vs. Me-Mow," he enlarged his liver 51 times a dog his size, preventing him from dying of Me-Mow's poison. One frequent use of his powers is Key Hand, which he uses to pick locks. He has also used his arm as a bow able to accurately shoot arrows at a short distance. As shown in "Mystery Train," he is also able to stretch himself to "create" an entirely new person, as long as they remain connected to him. In "You Made Me!," he is shown to be able to move objects through his body freely when he lets Princess Bubblegum jump into his mouth and then pushes her up through his back. Jake can be stretched by force as seen in "Ocean of Fear," when Finn stretched Jake's ears to avoid making contact with the ocean. Pendleton Ward has said in an interview that Jake uses his powers lazily and doesn't know their full extent. In "The Witch's Garden," Jake claims to have obtained his powers by rolling around in a magical mud puddle as a puppy, but in an interview Pendleton Ward stated that this is not how Jake got his powers, he just could not remember.
