'''Teenage Mutant Ninja Turtles & Other Strangeness''' is a 1985 RolePlayingGame made by Palladium Books revolving around the strange adventures of the [[ComicBook/TeenageMutantNinjaTurtlesMirage Teenage Mutant Ninja Turtles]], and later on, [[BadFuture a post-apocalyptic, mutant-infested Earth]].

The players get the opportunity to play as a variety mutated animals, having the ability to chose the species, mutations and special abilities that the character would receive. Possible characters range from tiny psychic bunnies to enormous anthropomorphic crocodiles to humanoids with almost no trace of their animal species.

The game series dropped in popularity and sales once the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987 cartoon]] and [[Film/TeenageMutantNinjaTurtles live-action films]] rolled out, which made (from the publishers' words) "the Turtles seem so childish that "no self-respecting teenager, even if he thought the Turtles were cool, or thought the Ninja Turtle game was cool, was going to be caught dead playing it.". By 2000, Palladium Books did not renew the license, because of license costs and the perception of the TMNT.

The books are as followed:

* {{Animal Wrongs Group}}: Doctor Feral had a run in with one of these when he was younger, despite overwhelming evidence [[KarmaHoudini all charges were dropped]].
* {{Bears Are Bad News}}: The Terror Bears [[NightmareFuel in spades!]]
* BlueAndOrangeMorality: Doctor Victor Oban Feral is [[CharacterAlignment "Scrupulous" in alignment]] and is described as 'unfailingly polite' even to his vivisection victims. He simply does not process that uplifted animals are beings worthy of moral consideration - the game backs up this moral relativism.
* {{Evilutionary Biologist}}: Doctor Feral...[[NightmareFuel Oh Dear Lord!]] Doctor Feral!
* {{For Halloween I Am Going As Myself}}: In the short story comic included in the Gamebook ''Don't Judge a Book'' The Turtles weren't originally aiming for this, Mikey was dressed up as a clown, Leo was dressed up as an alien, Raph dressed up like a punk rockstar and Don was dressed as [[WholesomeCrossdresser an old lady]]. However, burglars attempt to raid April's apartment and the Turtles have to fight them off. Their costumes are destroyed in the process, so they arrive to the party in nothing but their ninja accessories which (along with their PettingZooPeople looks) everyone assumes ''are'' their costumes.
* {{Little Bit Beastly}}: Mutants with 'Full Human Looks' – unlike the typical anime {{Catgirl}}, these characters normally just look like really ugly humans. Someone would say "That ugly lady looks like a skunk!" instead of "That skunk [[PettingZooPeople looks like a lady!]]"
* {{Small Taxonomy Pools}}: Lampshaded in the book as this was done for both reasons of space and the game designer's mental health, Animals that are very similar are sometimes lumped together. For example, coyotes and wolves fall under "Wild Canines", and eagles, hawks, and falcons are all "Wild Predatory Birds", with only slight differences between them (i.e., since a coyote is smaller then a wolf, it has more Bio-E to spend).
* {{Super Senses}}: The Super Senses one could acquire were Advanced Vision, Night Vision, Ultraviolet Light Advanced Hearing, Sonar, Advanced Smell and Advanced Touch
* WhatMeasureIsANonHuman: A human character (Doctor Feral) is considered a morally good person despite considering sentient animals to be fair game for vivisection. Mutant animals that turn on humanity in revenge for humans' actions against them (such as experimental subjects like the Terror Bears), however, are considered evil.
* {{They Would Cut You Up}}/{{Playing With Syringes}}: Doctor Feral is probobly half the reason Mutants have to have a {{Masquerade}} in the first place! Seriously, did they base half of [[TeenageMutantNinjaTurtles2003 Bishop's]] character off this guy?
