Well, there was really only one game (apart from "Mouse Mouse Gruffalo", a version of "Duck Duck Goose"), and that was "Stick the Wart on the Gruffalo's Nose"! I printed a picture of the Gruffalo's head onto two A4 sheets of paper and stuck them together. Then I bought some green stickers and cut them into wart shapes (you could use dots, but I couldn't find any poisonous green ones in time). I wrote the guest's names on the stickers too, so we knew who stuck what, where!
Even the Gruffalo got into the game!
