Mummipokey

Mummipokey is the second boss in World 2 of New Super Mario Bros. It is a mummified Pokey with red spikes.

In this battle, Mummipokey pops out of the ground at different places throughout the battle. Mario or Luigi must jump on its head three times to defeat it and gain access to World 3. However, the player can ground pound it to reduce the number of hits it takes; ground pounds deal double damage. The height of how far Mummipokey protudes from the ground varies, ranging from 2 to 5 segments, including the head. Sometimes Wall Jumps are required to get enough height to land on its head. Mummipokey can also spit out a projectile ball at Mario.

Access to World 4 can be earned if Mummipokey is defeated while Mario or Luigi is in their mini form. However, because the Mini Mushroom causes Mario/Luigi to get both smaller and weaker, they must Ground Pound Mummipokey to apply damage at all. The time it stays surfaced is dependent on its size: the more segments are exposed, the longer it is surfaced.
