Wan Sum Dung is a character in Mother 3, found only in the Death Desert in Chapter 3. It is a Dung Beetle, but does not consider itself to be one without any Dung to roll around and feels sad. Its name is a pun on 'Want Some Dung', which references this. If Salsa gives Wan Sum Dung the Dung that it desires, it will give Salsa either 5, 10, or 50 experience points depending on its judgement on the Dung's quality.
