Ghosts don't knock on the door

Marmot and Mishka are best friends, they always spend time together. It's great to play treasure hunters or sing and dance like they're on TV. But then one evening Mishka told the Groundhog that he had invited the Duckling to visit. The Groundhog doesn't want to play with the Duckling at all. Neither with Duckling, nor with anyone else: after all, everyone will prevent him from being friends with Mishka. So the Woodchuck firmly decided that the Duckling would not play with them - and he will achieve his goal! What confusion will his cunning plans lead to?
