Mouser mushroom

Mouser is waiting for the garden gnomes to come home from a hard day's work down in the diamond mine.

Oh wait. They were dwarves. And they lived in a cottage.

Meh.

Come to think of it: What did they actually do with the diamonds they found?

Is that ever explained? Do they just keep them in a vault and leave them there?

This is one of those story lines which should have been explored in the sequels.
