Mario wears Frog Suit, a power-up that debuted in Super Mario Bros. 3. The Frog Suit transforms Mario into Frog Mario and grants him the power to jump higher, swim faster, and resist water currents better, but he can only hop while on land. When Frog Mario is hit by an enemy, he reverts back to Super Mario. You can also try this costume in this fanart Super Mario In Frog Suit Sticker.
