Slug's Slugs

I hate snails. Dont you hate snails? Cuz I do. And that slug in the game hates em too. So he got a shotgun. to shoot the snails.

But wait! the shotgun is faulty and its bullets change every reload! the bullets are determined by 2 d6 die - each face has a different shell on it. It makes killing those pesky snails a lot harder - and more dangerous.
