Cat and mouse
The kids starts lying down in a circle, so that they are close together, two and two (each pair is a mouse hole). On pair is taken out – one is the cat, and the other mouse. The cat now has to catch the mouse, but the mouse can hide in a mouse hole, and get new energy. That means that the mouse can lye down close to one of the pairs on the floor. The person in the pair furthest away from the mouse, now becomes the mouse, and have to avoid the cat.
The game can be done more difficult by letting the person getting up, becoming the cat, while the previous cat now becomes the mouse.
