Thanks to a necklace Svolt could turn himself into a canine(almost at least) so he could visit Heidi in public.
Today he came to the training studio she worked at to surprise her. They walked to the backroom to be alone and Svolts stomach mouth showed the reason he came to visit.
Heidi is one lucky girl to have such a kind boyfriend like Svolt :)
