The cheerleading squad and Ron return to Camp Wannaweep — but the place has been cleaned up, and even Gil (who is also a mascot there) seems to have turned his life around. But Ron is suspicious.
Tropes used in this episode:
- An Aesop: Played with. After seeing a mascot won the camp spirit contest instead of them, Kim, Ron and Bonnie try to see this as a learning experience but can't come up with anything, especially not "Don't be paranoid". Kim is unsuccessful at thinking of a lesson, and Bonnie is too sullen to bother. But then it dawns on Ron: he recognizes that perhaps if Kim and Bonnie had put aside their differences and worked together, one of them could've won the contest. Bonnie would rather believe the moral of episode was "Cheer camp stinks". Ron can't argue with that.
- Animorphism: The muck pool mutates Gil back into Gill but more muscular while Ron becomes a humanoid beaver.
- Character Development: Discussed. Gil's doctor is disappointed that Gil had not changed his ways. Ron begs to differ, saying Gil did change, just for the worse.
- Continuity Nod: Mr. Barkin, who almost got mutated last time, groans, "For Pity's sake, NOT AGAIN!" when he sees the campers beginning to mutate.
- Dark Horse Victory: Kim and Bonnie both lose the competition to a guy from another school in a shark mascot suit.
- Enemy Mine: Bonnie and Kim use their acrobatic skills to help catch Gill.
- Evil Is Bigger: Gill’s mutated form is much bigger and muscular than before.
- Evil Makes You Ugly: Gill's mutated form is a larger, uglier version of his original form, in contrast to Ron's mutated beaver form which has a more buff, Top-Heavy Guy look.
- Falsely Reformed Villain: Gil pretends to have reformed just so Ron will seem paranoid but he actually wants to become Gill again.
- Full-Frontal Assault: Though concealed by muck and fur, both Ron and Gill are entirely naked in their mutant forms.
- I Warned You: Ron knew Gil is up to no good.
- Left the Background Music On: The dramatic music that played as Ron discovers that Camp Gottagrin is actually Camp Wannaweep turns out to be a band who thought that the titular camp was a band camp.
- Motive Decay: Gill previously wanted revenge against Ron for his mutation (in spite of it being his own fault instead of Ron's) but now he wants his mutant form back. But he still hates Ron (even before his first mutation).
- My Friends... and Zoidberg: Mr. Barkin addresses the group as "cheerleading team...and Ron" when he tells them about the cheerleading competition.
- Not Now, Kiddo: Kim ignores Ron when he tries to warn her that Gil has re-mutated, instead focusing on the cheerleading competition.
- Oh, No... Not Again!: Barkin's reaction when he Gil slimes him again..
- Out-of-Character Moment: Tara joins the campers in calling Ron a loser. Unlike the last time in camp Wannaweep when she was actually nicer to Ron than everyone, including Kim, this time, Kim is the only one who is nice to Ron.
- Produce Pelting: The cheerleading squads and other mascots throw tomatoes at Ron when it seems he's wrongfully accused Gil for nothing.
- Properly Paranoid: For the entire episode, Ron was suspicious of Gil and that he was up to no good. He was proven right when Gil purposefully re-mutates himself and attacks the camp.
- Sequel Episode: To "Sink or Swim".
- Shout-Out:
- When Kim says that he needs proof to accuse Gil, Ron yells, "You can't handle the proof!"
- Ron also refers to Gil(l) as "the creature from the muck lagoon."
- Skewed Priorities: Even as Gill is rampaging around the camp attempting to mutate everyone, Bonnie is more concerned about Kim "taking all the credit" and winning the Spirit Stick instead of her.
- Subverted Suspicion Aesop: Ron insists that Gil is up to no good, keeping track of the "suspicious" things he does and tracking him around camp. But it turns out he was right.
- Super Spit: Gill's spit is mutagenic.
- Tempting Fate:Ron: And you know, you'd think at some point they'd run out of rotten vegetables to pelt me with!cue to getting thrown
- Tired of Running: When Ron decides to stand up to Gill.Ron: As of right now, Ron Stoppable is all done running.
- Took a Level in Badass: Both Gill and Ron.
- Gill’s mutated form is much bigger and muscular than before and now he has the power to camouflage.
- Ron mutates into a giant beaver with a Prehensile Tail and goes toe to toe against the mutated Gill.
- Wanting Is Better Than Having: Deconstructed. Gil wanted to have a normal life again, but after he was cured of his mutated condition, he found he missed being a mutant. Especially because of the power it granted him.
- Wrongly Accused: Subverted with Gil. He appears to have become a nice, normal guy, but then he turns out to be out to mutate everybody...again.
- You've Gotta Be Kidding Me!: Gill is not amused when everyone thinks his One-Winged Angel form is a mascot costume.
