Svalgurok is the Nordic Outdoor World of Slides in the Rulantica water world. The serpent Svalgur guards the paradise of 100 playing opportunities with a watchful gaze. Small children are absolutely prohibited, and so is Snorri! But the lovable mascot from Rulantica won't let the fun be spoiled and tries by all means to go sliding. Will Snorri manage to outsmart Svalgur?
