A problem with owning a ground type pokemon is their tendency to enjoy digging. While it's definitely important enrichment for them, it can easily lead to trainer-pokemon seperation.
In these particular cases, researchers have found that diapering up a burrowing pokemon is enough to prevent them from digging away without warning. The poof of the diaper will get stuck in the hole and prevent the pokemon from going any further, plus it keeps them in place to make it easier for you to find them!

Decided to do more diapers with stuckage again, at the suggestion of a friend. Think it fits well for a mole pokemon since they dig so many holes!
