Looking for a fun children's book? Then go for De Gröffelo! Frans Pollux translated the world-famous children's book The Gruffalo into Venloos. The result? De Gröffelo, a creature that only a small mouse knows exactly what it looks like. But do the fox, owl, and snake believe the little mouse? And does the Gröffelo really exist, or is the mouse talking schaele wazel?
