Ninni could not even imagine that one day she would come to the "Shop of Nightmares", and there it would snowfall, as if it was winter outside! Pepper, of course, has fun: he flies to himself and catches snowflakes with his tongue. And so I want to make a snowman… Only the dental trolls are completely frozen, even in wool socks! Ninny, Pepper and the Stranger will have to figure out why it has become so cold in the "Shop", and the terrible yeti will help them solve this riddle. Together they will equip an expedition to the roof and find out the reason for the sudden "ice age".
