Tobias Tozt has long been looking forward to Christmas Eve - and of course to his guests: his best friend, the lion, the elephant and the giraffe. He is in the process of preparing a special Christmas dinner and decorating the tree as it rings. His guests are too early! But it is only the lion at the door and he is very excited. There is something wrong with the kangaroo. Tobias must come immediately, because the zoo director is already on Christmas leave.
