Frog Pirate

Frog Pirates are a species of frog in Super Mario World 2: Yoshi's Island and Yoshi's Island: Super Mario Advance 3. They live in the swamps and wetlands of Yoshi's Island and are found primarily in World 3. If a Yoshi comes too close to one, it will lash out its tongue and try to steal Baby Mario. Stepping on its head only disables it for a moment, so Yoshi should instead try to throw an Egg at the frog or swallow it. Spitting out a Frog Pirate will only make it fall off the screen, enabling it to respawn later.

The World 3 mid-boss Froggy is based on this enemy, and unlike other bosses in the game, bears no visible differences to the enemy he is based on. In the Japanese version of the game, Froggy and Frog Pirates have the same name (Gerogēro).

Super Mario World 2: Yoshi's Island

 * Shogakukan guide: なが～い舌をのばして赤ちゃんをさらう大ガエル. タマゴを当てるとしばらく気絶するので、そのスキに食ベてしまおう. (A large frog that snatches the baby by stretching out its long tongue. If you hit it with an egg, it faints, so eat it while it's still unconscious.)
 * Player's Guide: These larcenous amphibians have tongues even longer than Yoshi's, and they'd love to steal Baby Mario!

Yoshi's Island: Super Mario Advance 3

 * Shogakukan guide (shared with Froggy): 長い舌をのばして、赤ちゃんをさらう大ガエル. タマゴを当てると気絶するので、その間に食ベてしまおう. ワールド3-4ではボスとしても登場. (A large frog that snatches the baby by stretching out its long tongue. If you hit it with an egg, it faints, so eat it while it's still unconscious. It also appears as a boss in World 3-4.)
