S2E13 Tricky Trolls

Hilda from Norway has arranged a picnic basket for her school outing and asks Jett to join her. While enjoying the picnic, Jett playfully frightens Hilda by wearing a troll mask. Startled, she accidentally drops the basket, which mysteriously shifts and vanishes into a hole in the ground. Are trolls up to no good in this situation?
