Frogs are the second most frequently seen fodder in the Spyro series and minimal enemies seen throughout few of the games. Only one known frog, Fredneck, is a character who isn't a fooder.

Spyro the Dragon

In Spyro the Dragon, Frogs are only seen in Dark Hollow as fodder. They've much resemblance to Big Gnorcs, and look somewhat dimwitted.

Spyro 2: Ripto's Rage!

In this game, they've changed a lot, for they've gained: black eyebrows, a yellow, throat, and stomach, and a different figure; and have lost: teeth, and a set head. Here they're far more common appearing in two homeworlds, and realms, Summer Forest, Autumn Plains, and Mystic Marsh, as opposed to appearing in just one realm.

Spyro: Year of the Dragon

In Year of the Dragon, they have been changed, only to match accordingly to the areas of which they would reside in. They are seen only as fodder in two different realms and a homeworld (Sunny Villa, Charmed Ridge, and Evening Lake), reverse of the second game.

Spyro: A Hero's Tail

A frog named Fredneck is a resident in the Crocovile Swamp in the Dragon Kingdom.
