Amphibian Assault

Go To
He'll make you croak.
And the Lord spoke to Moses, "Go to Pharaoh and say to him, 'Thus says the Lord: "Let My people go, that they may serve Me. But if you refuse to let them go, behold, I will smite all your territory with frogs. So the river shall bring forth frogs abundantly, which shall go up and come into your house, into your bedroom, on your bed, into the houses of your servants, on your people, into your ovens, and into your kneading bowls. And the frogs shall come up on you, on your people, and on all your servants." ' " ... So Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land of Egypt.
Book of Exodus, 8:1-4,6

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.

  • The eight crassigyrinus in Prehistoric Earth prove every bit as dangerous as the single crassigyrinus encountered in Prehistoric Park by virtue of the species first introducing itself into the story by virtue of one of them lunging out of the waters of its carboniferous swamp homeland in time to snap up a meganeura for lunch, with all eight of the critters ending up needing to get muzzled before they get sent back to the titular park for the sake of being prevented from severely hurting anyone with their massive teeth before they're placed into their new home at said park.
  • Several of the prehistoric amphibians rescued for the titular park in Prehistoric Park Reimagined prove rather aggressive and perfectly willing to attack the rescue team and other park staff members (albeit, for such realistic reasons as hunger and territoriality), with one of the encountered crassigyrinus managing to bite one member of the rescue team on the ankle and an entire float of them very nearly managing to eat one of the veterinarians when she accidentally falls into their exhibit, several temnospondyls behaving remarkably similar to crocodilians, and even the less aggressive species being handled with appropriate safety precautions in place just in case they turn out to be venomous or poisonous.

Now that's some way to spice up a Sunday game.

  • Pyribbit from Kirby: Triple Deluxe is a huge, regal-looking, fire-breathing frog that lives in a volcano.

However, Taranza provokes him into attacking Kirby for the fifth boss fight, and he's quite infuriating. Pyribbit's fighting style involves bouncing all over the place and causing dangerous volcanic eruptions, and once he Turns Red, he spends most of his time in the background, where he's impossible to hit!

He wishes to conquer Amphibia and the human realm, and poses quite a big threat to both worlds.
