You'd better hang Loki's son Fenrir around his neck with a chain called Gleipnir. Although it looks like a mere silk ribbon, it consists of six miraculous ingredients: the noise of cat walking, a woman's beard, a mountain root, a bear feeling, fish's breath and bird saliva.
When the chain breaks, Ragnarök occurs and the wolf eats Odin. So you better check it :)
