Frog Mario

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

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. The Frog Suit will also prevent the player from slipping on Ice Blocks.

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.

A form of Frog Mario appears in Paper Mario: Sticker Star when a Frog Suit sticker is used; it only overlays the sticker onto Mario, rather than turning him into Frog Mario. With his Frog Suit, Mario can dodge enemy attacks by jumping, and his jump attacks are also stronger.

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 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. It only lasts until Mario takes damage (this physically removes the Frog Suit, as in Super Mario Bros. 3) or wins the fight.

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.
 * Although the form itself doesn't appear in Super Mario Odyssey, Mario can take control of a frog using Cappy's capture ability.
