Gray, grumpy Julius has a brilliant idea: he wants to organise a big party in his living room. So he starts looking for guests. Luckily enough, there are all kinds of animals dwelling on the opposite page. Julius ventures out into the jungle, where he locks different wild creatures in cages before carefully labelling and meticulously stacking them in his living room. But tigers, giraffes, plants and butterflies were never meant to be imprisoned, and when Julius tries to squeeze one last cage into the room, all the cages explode, and their occupants are set free!
