Summer has arrived, it's time to go to summer camp, and ever eager McGee couldn't be more thrilled to spend it at Camp Sunnysmiles, the most elite summer camp/resort in the country—even if he has to spend the summer with his overbearing sister Suzi. Thanks to rich jerk Jordan Buttsquat, he, along with aloof Gretchen and big, softhearted Squirt, wind up heading to Camp Lakebottom. It's a gloomy wreck of a camp, staffed by a friendly zombie, a fancypants sasquatch, and a short lunch-lady. Though spooked at first, the trio find out Camp Lakebottom isn't such a bad place to spend the summer after all. The only thing that stands in the way of their summer fun is McGee's rivalry with Buttsquat over whose camp is better.
Attention Whore: Suzi must always be the best most prolific person in the area, even if it means letting her little brother get hurt to stay at the top. Or say cursing an entire play and calling upon dark curses that leave her a lightning shooting, wild-haired monster.
Cosmetic Catastrophe: Gretchen does this to herself when she tries to prove she is girly enough to enter Camp Sunnysmiles beauty pageant in "Ring Around the Gretchen". When she buries her face on her bed in sorrow, her face sticks to the blanket.
Cowboy Episode: In "High Plains Garbage Eater", it's Western Week at camp and the gang finds themselves in the middle of a good ol' fashioned showdown with mutant raccoons, over garbage!
Dark Is Not Evil: Lakebottom is a gloomy pit, filled with monsters and all numbers of strange things. And they're all friendlier than the jerks at Sunny Smiles.
Did You Get a New Haircut?: In "Mindsuckers From the Depths", Squirt gets a huge, evil leech attached to the top of his head. Armand notices there is something different about him and wonders if he is using a new cologne.
Does This Remind You of Anything?: After Buttsquat banned gum, Suzi and a number of other Sunnysmiles campers started acting like they were drug addicts on withdrawal.
Early-Bird Cameo: Chipper from "Cheeks of Dread" made his first appearance in the opening.
Forbidden Fruit: Gum becomes this for Suzi after Buttsquat bans it. Lampshaded, "I don't even like gum, but now I gotta have it!" after which she starts gnawing used pieces off off the bottom of McGee's bed.
Made of Explodium: In "Slimey Come Home" when the giant crab rips one of the Sunnysmiles cabins out of the ground and skips it across the lake, it explodes after a distance.
Meat-O-Vision: When McGee and Buttsquat are lost in the wilderness and starving they start to hallucinate all kind of things of food; including a pile of leaves as a giant plate of nachos and a tree stump as a giant sundae.
My Beloved Smother: Sawyer's mom, who is not only sickeningly doting, but an old-school undead brain-eating zombie who tries to get her son to start noshing on noggins again.
Although a throwaway line Played for Laughs at the end of "Zombie Dearest" has him say that he does desire to eat brains (and regularly fantasizes about eating the brains of the campers), he just chooses not to act on it so he can be a camp counselor.
Overly Long Gag: Papa Gnome seems to have spent the greater part of the episode repeating "Or else!" and petrifying things building up a rather big pile.
Puppeteer Parasite: "Mindsuckers from the Depths" has an army of mind control leeches hell-bent on world domination with their leader, the largest, taking head on Squirt.
Similar Squad: The kids find Camp Bottomlake in an underwater cave, containing Fish People versions of themselves and a Giant Squid version of Buttsquat. There aren't any counselors to be found though (it's implied that the Buttsquid may have had something to do with that).
