Piglet Racing, with stack movement which works a bit like Monster Fressen. Or in the words of the rules:The merry trunk gang consists of seven multicolored piglets, who love nothing more than running through the meadows - on roads, which are so narrow that they cannot pass the other pigs - except, if they stand on top of one another! Naturally, they know how to do this, as they are not normal piglets, but genuine circus piglets! And even if they do not run a race, they gladly demonstrate acrobatic exercises or set up themselves in marvelous pyramids.Ages 4 and up. - BoardGameGeek
