Frog Mario

"Oh me, oh my! You've been transformed! Shall I change you back with this wand?"

- Kings

Frog Mario is an alternate form of Mario and Luigi that can be attained by acquiring a Frog Suit in the game Super Mario Bros. 3. Frog Mario can swim faster than regular Mario, allowing him to overcome currents in his path. Controlling Mario while swimming is also easier, as he can stop instantly, in a single spot in the water, and swim in any direction. However, Frog Mario's walking and running ability is greatly decreased. In fact, Frog Mario can only hop on the ground like a frog. As such, Frog Mario's jumping ability is greater than regular Mario's. Also, Frog Mario can run when carrying an item such as a Koopa Shell. It will also prevent Big Bertha from eating the player.

In The Adventures of Super Mario Bros. 3, Princess Toadstool and Toad were also able to use the Frog Suit. King Koopa also had the ability to transform himself through the use of a Power Pendant.

Frog Mario makes its Paper Mario series debut in Paper Mario: Sticker Star, where he appears when a Frog Suit sticker is used. With his Frog Suit, Mario can dodge enemy attacks by jumping.

Frog Mario also appears as one of the unlockable Mystery Mushroom costumes in Super Mario Maker. Also, Weird Mario may appear in this form if a Warp Door is knocked in Edit Mode in the Super Mario Bros. 3 theme.

Frog Mario also appears in Paper Mario: Color Splash, via use of a Frog Suit card. It works like it did in Paper Mario: Sticker Star, letting Mario jump over enemy attacks.

Trivia

 * In the Club Nintendo comic "Mario will hoch hinaus", Mario is seen jumping around, saying, "It's great to be a frog", despite not wearing the Frog Suit.
 * Two transformations have this same underwater effect: Shell Mario and Penguin Mario.
 * It is impossible to complete some levels while wearing the Frog Suit, particularly Fortress Levels, as there are sections that players need to crouch to pass.
 * Early concept art for Super Mario Bros. 3 shows that Frog Mario would be able to use his tongue to slurp up and spit out enemies, which would later become one of Yoshi's abilities in Super Mario World.
