Madame Grunty

Madame Grunty is a character in Banjo-Tooie. If you go inside her tent in Witchyworld, she might give you eggs, feathers, or a beating, or if you vist her enough she will give you a cheat code that will let you read the signposts in Jiggywiggy's Temple that tell you how to get all the Jiggies.

It is possible to assume that, due to the fact that Madame Grunty shares the same name and avatar as Gruntilda, that they are the same person. This would be odd though, due to the fact that she gives you feathers and eggs on occasion.
