A camping trip goes pearshape for Mordecai, Rigby, Margaret, and Eileen — and things get worse when they encounter a half-human, half-deer creature.

!! Tropes

* BestialityIsDepraved: It's implied but not outright stated that the deer-man was conceived and abandoned by a human woman who slept with a stag.
* DeadGuyOnDisplay: After the deer-man dies, the Park Ranger announces he's going to have the body stuffed and dressed to put on display.
* EpicFail: Rigby says he didn't bring the tent because he wanted to bring the tarps... ''which he forgot as well''.
* HalfHumanHybrid: The protagonists encounter a half-human half-deer in the forest. His features are very clearly defined from each other and randomly placed, with a stag head on a human torso for starters.
* MathematiciansAnswer:
-->'''Park Ranger:''' Pine Ridge or Valley Fields?
-->'''Mordecai:''' Yeah.
-->''(The Park Ranger puts a DeathGlare in frustration)''
* SpecialGuest: The deer-man is voiced by Creator/RobertEnglund, who is well-known for playing iconic horror villain Freddy Kruger from ''Franchise/ANightmareOnElmStreet''.
* SuddenlyVoiced: The "deer" shouts at Margaret after the latter tries to grab another branch for the site.
* WhamLine: Margaret tries to fetch more branches for shelter and once again encounters the "deer", who starts speaking out-of-nowhere:
-->'''Deer-Man:''' Take filthy hands off branches!
