Limbo

Limbos are skeletal enemies found in Mad Monster Mansion. Although their enormous heads appear to be large targets and most attacks will shatter their fragile bodies with relative ease, these undead baddies are particularly difficult to exterminate, as their bodies will reform within a few seconds of being hit.

Even so, Limbos are slow to react and can either be pushed over or completely ignored in some situations. If they prove themselves to be especially problematic, or if Banjo and Kazooie are low on health and could use some extra honeycombs, a quick use of the Wonderwing will put these corpses to rest once and for all.

Trivia
Limbos appear to resemble the Stalfos from The Legend of Zelda series.
