My Gym Partner's a Monkey
It's all a massive coma hallucination on the part of the main character.On his way to school, Adam Lyon was hit by a car and became comatose. He then proceeded to hallucinate that he went to a school full of animals, because what young child wouldn't love that?
The school is a secret, black-ops genetic research facility.The school only lets "animals" in to hide the human/animal genetic hybridization that they're doing to create a race of intelligent animals to use as living weaponry. Adam is inserted into the school to spy on the horrific results and report back to unseen superiors.
The series is thinly-veiled racist propaganda.The theme song talks about how the main character, Adam Lyon, is sent to an animal school because "L[i]on's my last name", which sounds suspiciously like anti-Semitism. Besides that, the show obviously reflects "Jim Crow"-style racism against blacks: animals are only allowed to go to special, "animal" schools, and they are shown as uncontrollable savages on many occasions.
Jake harbors a strong homosexual lust for Adam.Seriously here, pick any episode and you can find at least three blatant hints of this.
Adam is a LionNot only is he a lion, but he is also the toughest and most dangerous creature in the school. But he has multiple personalities, one of which is Adam L"y"on. This is why Principal Pixiefrog is so quick to blame Adam for everything and why Adam survives all those Amusing Injuries. Anyone who strays from Adam's delusions is harshly punished. Ingrid's and Jake's attractions to him are because of their natural attraction to an alpha-male: the L"y"on personality isn't one, but the L"i"on personality is.
Adam is not only a Lion, but also an extreme reverse furry.
Adam is insane and believes a normal school is an animal schoolHis human friends show up once in a while when the madness wears off. Sometimes it doesn't wear off right away; that's why his female love interest shows up in a giraffe costume. This explains the costume; if the world of the show is what it appears to be, then wearing that costume would be like wearing blackface.
Adam is the only human left on earth.The others tolerate his imaginings of his human friends out of pity.
Adam has a weird imaginationHe probably mistook an academy for geniuses (or a private school, as that shark isn't really smart) for an animal school, and is imagining everything. The other "animals" are kids who mostly reject him because he has issues; since Jake also has psychiatric problems and is a furry, he likes Adam's imagination.
Everyone's human. Jake's just been feeding Adam hallucinogenics since they met.Because Jake's enough of a Jerk Ass to enjoy it.
Nurse Gazelle is only acting dumb and is really Ax-Crazy and enjoys terrorizing children.Proof of this in The Hyena And The Mighty episode where she terrorizes Rufus Hyena.
Windsor Gorilla and Rufus Hyena are in a gay romantic relationshipThis troper ships them, anyway. He called Rufus his sweets when the hyena started crying.
