Pongwiffy - A Witch of Dirty Habits by Kaye Umansky
Pongwiffy is a witch of very dirty habits. She also has a problem - the cave she has just moved into is filthy (although that's not the problem, Pongwiffy likes it like that) but also has extremely noisy neighbours. The neighbours (not unsurprisingly, as the cave is in Goblin Territory), are Goblins, and as well as being very, very stupid, are very, very noisy. They are so noisy that Pongwiffy can bear it no more and enlists the help of her best friend, Witch Sharkadder, to find her somewhere else to live. Which is nearly the end of one very beautiful friendship A laugh-out-loud story that is witty and clever, enticingly mixed in with much sludge, slime and very bad habits.
