Klaut has always had a knack for finding things and is often setting out in search of oddities to bring home. This eventually led to him finding Biscuit as a small abandoned puppy. Dwarves don't know that much about dogs; after all, dogs are  mans best friend after all not dwarfs, so Klaut was surprised when Biscuit kept growing and growing until he stood taller than the dwarf. Biscuit, despite being a bundle of surprises, is a very good boy and helps Klaut by bringing back just as many curiosities as the dwarf.
