KLAUS is still in PETER’s house and is about to leave, but PETER first wants him to try a means of transportation he has, which is guarded by a good TROLL name CROC, and it’s a balloon. While CROC is holding the rope and KLAUS and PETER are on the balloon, CROC absentmindedly lets go of it and KLAUS and PETER are lost in the sky. They are rescued by some gnomes. To thank them, KLAUS helps them in a case with their dog ARTICA.
