Synopsis involving Callum
Callum asked for a special bagpipe that not only plays but blows bubbles, too. He believes that making bubbles with it he will attract Nessie so he can meet her. His idea works at first but he blows a bubble so big that it remains attached to his bagpipe and lift him in the air, rendering the help of Jett needed. The bagpipe then falls into the lake prompting Mira to come to help retrieve it, but only with the intervention of Nessie herself everything will come to a happy end.
