Crocodile
Frog
Salamander

Frogs and other amphibians. Croak for call? And pulled from the web.

The group of Frogs is commonly called an Army. The other collective nouns used for the group of frogs are box, bundle, colossus, and nod. However, terms such as gathering, troop, and bevy can also be used. But the army of the frog is relatively widely used the collective name as compared to others.

Alright, it's that time and people are getting excited on Discord again.
Here's all the collected animal requests so far since August:

Genet (small feline)
Fisher cat (mustelid)
Fishing cat (small feline)
Quokka
Colossal Squid
Kraken
Other Cephalopods
Elephant
Koalas
Pygmy Marmoset
Other pygmy animals, like pygmy hippos
Swan
Sparrow
Aivren
Wyvern
Drake
Miniature (french) bulldog
Corgi
Puggle (semi-aquatic)
Puggle (canine)
Teadragons
Mongoose

Add Sharks of all varieties (e.g. hammerhead, great white), manta rays, octopus, and I second the kraken, colossal squid, and wyvern previously mentioned.

I'd really like to see frogs and lizards
