Piňata Party. Grizzy finds a birthday piňata in the ranger's living room. The idea of bursting open a papier-mâché statue with a bat like it says in the instructions pleases him. The Lemmings, who prefer to use it as a toy to swing from, are determined to stop Grizzy from destroying the piňata.

In a vast natural reserve lost in the middle of the untamed wilderness, there is a small haven of human civilization: the forest ranger's house. Because he is (from his point of view) the most evolved animal on earth, the bear Grizzy feels it's only natural that the ranger's house becomes his territory as soon as its owner is away. No other animal dares to contest this 'bear's privilege,' except the most inoffensive, stupid and ridiculous mammal family that exists: the Lemmings - who also move into the house as soon as the ranger is gone. Grizzy and the Lemmings lead a merciless battle over the house in an atmosphere of total madness, where the two adversaries constantly try to outdo each other with nasty tricks!
