Frog

Frogs are a species of animals that live on both Earth and on 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 Frog as well. The young tadpoles comprise a greater part of the population than the Frogs, of which there are only two.

Smaller Frogs latter appeared in Super Mario World 2: Yoshi's Island where they could be seen jumping around in some World 3 levels, they didn't had any effect on gameplay and were mostly part of the background.

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 them by clapping. Each clap would make a Frog get fatter and would also make him start floating. After Donkey Kong clapped enough, the Frog would explode. Frogs also appeared in Diddy Kong Racing at the starting area of Adventure Mode, where the player could run over them with their vehicle to squash them.

In Mario Party 6, some Frogs can be seen in the background of Towering Treetop, and Super Mario World 2: Yoshi's Island even features small, red and green Frogs (that are unaffected by gameplay and were simply placed in the game for decoration) in the foreground of swamp stages. Wart from Super Mario Bros. 2 is also a Frog, and, in Super Mario Bros. 3, there is a Frog Suit that allows Mario to become Frog Mario and Luigi to become Frog Luigi; Frog Pirates and Bopping Toadies, other Frog-like enemies, also appeared in Super Mario World 2: Yoshi's Island and Super Mario Land 2: 6 Golden Coins, respectively.

Trivia

 * In an E3 demo of Paper Mario: The Thousand-Year Door Hooktail had a strong dislike toward Frogs, however this was changed and Hooktail was given the hatred of crickets.
