Mummipokey is the second boss in the game New Super Mario Bros. for the Nintendo DS. It is a mummified Pokey that will appear in the last level of World 2, and shoots spikes at Mario or Luigi, or just tries to ram into them. In order to defeat it, Mario and Luigi either has to jump on its head, or shoot fireballs at it. If the plumbers defeat it in their miniature form, they are able to access to the optional World 4.
Mummipokey slowly burrows underground when having five segments, twice as quick with three and instantly with a single segment. It can also be defeated with fifteen fireballs shot at it.
