Amphibian Assault

Go To
He'll make you croak.
Let us contemplate the humble amphibian. Placid, fly-eating, harmless creatures. Traditionally used as ammunition for little boys wishing to gross-out little girls.


In fiction, amphibians can be large and aggressive enough to be a bona-fide threat, with a sticky tongue very conducive to devouring humans in one gulp. Even normal-sized ones can be dangerous, as these often have some sort of poison attack. (Several Real Life species are indeed poisonous, but only if you try to eat them, as a rule.)

Wizards and witches may sometimes summon these as an attack. After all, turning people into toads is traditional, so why not make use of them afterwards?

Although rare, these can be good guys as well. Note that this trope also includes other amphibians.

See also Amphibian at Large, which many examples also qualify for.

Not only it can breath poisonous gases, it can shoot out chemical globs out of its body that are extremely flammable.

    Tabletop Games 
  • Dungeons & Dragons:

    • Deities & Demigods Cyclopedia, Melnibonean mythos. Quaolnargn is a huge (8 feet tall and wide) frog-like demon. Its bite drains Life Energy, causing the loss of 4 Character Levels as well as 1-10 Hit Points.

  • There was a ruleset for Warhammer 40,000 on the game's official website that had special rules for jungle critters for the Death World of Catachan. Where other jungles have frogs that are merely deadly to eat, Catachan apparently has frogs that explode when startled. The rules posited that a number of frogs are randomly placed on the battlefield before the beginning of the game and moved every turn, placing a large explosion template on the table upon contact with any ground forces. Now that's some way to spice up a Sunday game.

  • In Cuphead, Ribby and Croaks are a duo of giant boxing frog brothers who are some of the many debtors who sold their soul to the Devil and fight Cuphead and Mugman in a boss fight when the latter came to collect their contracts. Much like everything else in this game, they are very formidable opponents, so prepare to die a lot.

Cue the shed said frog is in collapsing to reveal it has mutated into a giant and eats Calipso.

  • Vinesauce: Invoked. Vinny absolutely despises Bunji the frog, a character from The Gigglebone Gang series of edutainment games. Whenever Vinny plays the games on stream, he talks about Bunji's Extreme Omnivore habits in a scathing way.

    • The 2012 Nickelodeon series reimagines Mona Lisa as a Salamandrian, a member of a race of alien salamanders. She is a capable warrior and ally of the Turtles. The show also has a villainous example of this trope in the form the Newtralizer, a member of Mona's race who is an evil bounty hunter.

    Real Life 
  • Many extinct species of amphibians were enormous, such as the 4-5 meters long Koolasuchus and the 9 meters long crocodile-like Prionosuchus (the largest amphibian known so far) and given how aggressive creatures such as toads and frogs can be when hunting, it's reasonable to assume they were fairly dangerous and aggressive as well given their physical characteristics and size.
  • While not actively dangerous, the poison dart frog secretes a poison that can knock out or even kill any predators or people that dare to touch it.

How well does it match the trope?
