Mummipokey

Mummipokey is the second boss in World 2 of New Super Mario Bros. He is a mummified Pokey.

In this battle, Mummipokey pops out of the ground at different places throughout the battle. Mario or Luigi must Wall Jump on its head three times to beat the boss and access World 3. It is also possible to just wait for it to pop up at a low height and hop on its head normally.

However, if Mario wants to access World 4, the plumber can defeat Mummipokey as Mini Mario. Mario must Ground Pound Mummipokey's head three times as Mini Mario to access World 4.

Trivia

 * Mummipokey is possibly a Skellokey, an undead Pokey which happens to look rather similar to Mummipokey.
 * It is also possible that Mummipokey is a Pokey Mummy, another undead Pokey with a similar name; however, he looks little like a Pokey Mummy.
 * An issue of Nintendo Power also (incorrectly) stated Mummipokey to be a sandworm.
 * Mummipokey looks like one of the Pokeys from Super Mario 64.
