The events of "Lumpus' Last Stand" never really happened—they're the result of some really weird dream that someone on the show had.
Acorn flats is really a reform camp
- They take every opportunity to harass the Bean Scouts if they see a boat coming to them, even when they know they’re invited, but that could just as easily be from Miss Mucus’s influence.
- They had little to no remorse stealing a float the Bean Scouts made sooner, then just thinking not entering at all meant they lost to them.
- The fact they have various activities designed to keep them busy, rather than make trouble.
The squirrel Scouts influenced Jane Doe’s Decision.
- In the episode "Hello Summer, Goodbye Camp", we learn Jane Doe was almost going to send the Bean Scouts to a math camp but why would she? With how Miss Mucus as well as the other Squirrel Scouts hate the Bean Scouts, who's to say they didn't influence her decision to send them to a harsh looking camp they'd probably hate?
The blue turtle from "Slap Happy" is an elderly Filburt
- If the finale can imply that Heffer is the former Scoutmaster of Camp Kidney, maybe being in a Brotherhood of Funny Hats is what Filburt got up to in his old age. Mr. Lawrence is even using the Filburt voice for the turtle.
