In “Hug Wolf,” while searching for the deadly Blight Tree, Finn and Jake are ambushed by an alpha hug wolf that gets its heart-shaped paws around Finn. Jake manages to burn down the Blight tree. He asks Finn if he is alright. Finn’s suddenly filled with affection, and he can’t stop hugging people. He does this this to Beemo after they return to the tree fort, and Jake is playing video games.
After this hug, Finn remembers that the hug wolf “didn’t even tell me it’s name,” and Jake thinks he better sleep this one off. As the nights wears on, Finn looks like he has a bad sickness, or bad dreams.
While picking up candy litter, Finn is confronted by Cinnamon Bun for the aggressive hugs he gave the night before, but he has no recollection of the events. He doesn’t believe it happened, but Jake points out that Finn was huggy the night before, and takes him to the library where they look up some information on hug wolves.
Finn became a hug wolf after being hugged by an alpha on a full moon, and Jake tries to purge the craving out of his best friend’s system. Weighed down with bags of frozen peas, Finn still can’t resist the force of nature that is the hug wolf, and he undergoes the full transformation into a beta hug wolf.
The entire Finn beta wolf sequence is quick and funny, beginning with his “hugs for buddies!” howl, then the attack on Mr. Cupcake, and the final scene where Finn sneaks into a gum drop’s room but is fought off by her father who tries to shoot Finn with a candy cane shotgun.
Jakes finds Finn in a small stream the next morning, and he tells Finn that in his hug lust, he hugged everyone in the Candy Kingdom.
Unable to deny who he has become, Finn demands to be locked in the candy dungeon, and the candy people decide to leave Cinnamon Bun as the prison guard. After getting a taste of Finn’s hugs, Cinnamon Bun wants more. CB releases Finn so he can feel his hug once more.
Jake is tracking down the alpha hug wolf to put an end to its reign of gentle terror. As the hug wolf prepares to attack, Finn, as the beta hug wolf, leaps into the fray and the two hug wolves hug it out, shooting little heart sparks as they battle. Then, they cause a nuclear heart explosion, and they both turn back into who they were before. Finn no longer wants to hug anyone. Jake suddenly wants a hug from the lady that the alpha wolf turns into, because she is very pretty, but then she turns into the Blight Tree and attacks him.
