Although a bit too late for Halloween, here’s another enemy from New Super Mario Bros. on the DS.
Splunkins are squat little pumpkins with legs that roam around the floors of World 8 and Ghost Houses in a manner very similar to Goombas. Though they are a bit tougher and Mario needs to jump on them twice in order to defeat them.

Looks like a simple model good for beginners, though take care with closing the parts.
