In the Mushroom World, there is a pond inhabited by large, anthropomorphic, sapient Frogs in the duration of Super Mario RPG: Legend of the Seven Stars,  Mallow was raised by the Frogs, specifically Frogfucius and believed that he, himself, was a Froggy as well. The young tadpoles comprise a greater part of the population than the Frogs, of which there are only two. Frogs also appeared as enemies in Yoshi's Story during Stage 4-4: Neuron Jungle. They swarm any Yoshi crossing the lagoon. Although any Yoshi could eat them, Green Yoshi liked them best.

During Donkey Kong: Jungle Beat there were Frog enemies in Banana Kingdom and other kingdoms as well, Donkey Kong had to beat by clapping. Each clap would make a Frog get fatter and start floating. After Donkey Kong clapping enough, the Frog would blow up.
