Gillyweasels

Gillyweasels are very small creatures which have over-large heads, bat-like ears, and very large eyes, which give them the appearance of always being in total fear. They walk upright on two legs which are very thin, as are their arms, and they also have long thin tails, similar to a rat’s.
Their skin is a sort of taupe colour and they have long hair which is so fine that you can see their scalps through it. The male and female look so alike it is difficult to tell them apart, apart from the fact that the male gillyweasels wear ragged ill-made trousers and tops, and the female wear equally ragged dresses. They have claws on their hands and feet for digging as they live in underground burrows. The main gillyweasel character in these books is Zale
