Toad's Super Toad form can seemingly only be activated by Toad touching a Fire Flower. Upon touching a Fire Flower, Toad's colors become inverted and he gains many powers, such as the ability to shoot fireballs, as well as flight (similar to Super Mario and Super Luigi). Toad seemingly loses his Super Toad powers after some time.
As Super Toad, Toad's color scheme becomes inverted, with Toad gaining a red cap with white spots and a white vest with red pants as Super Toad; Toad's Super form has the same coloration as his regular form did in the first three episodes of The Super Mario Bros. Super Show!
