Mummy Toadlets are uncommon enemies that appear in A Koopa's Revenge 2 and only appears in World 2-5 Forsaken Pyramid. The main attack is just walk, like normal Toadlet, however should the player fire a fireball at a Mummy Toadlet it will speed mush faster across the stage for a few seconds until they eventually get defeated. Unlike normal Toadlets, they can be used as helpful tool to get across gaps and even a single Large Mummy Toadlet can help you to get across the spikes.
Big Mummy Toadlets are found in the Forsaken Pyramid. It can help Koopa go across a large path of spikes. Unlike normal mummy toadlets, Big Mummy Toadlets can't be defeated in any way (not even Screw Attack kills them)
