A fully-grown elephant with Dwarfism. This particular elephant stands at about 5ft tall.
Oh! Jiminy gosh! I just assumed if someone was asking, you already knew! Hm. Discworld is a sort of parody of the whole fantasy genre. It's a series of novels that all take place in the same universe, on a planet that's sort of like ours (except flat, and floating through space on the backs of four giant elephants who stand on the shell of a massive turtle). It's inhabited by casts of genre-aware characters who are all pretty unconventional heroes, and was written by the late Terry Pratchett.
