After numerous adventures in New York, the favorite Misiek of the whole world thought he could finally relax. Nothing could be more wrong - a new adventure is just around the corner! And literally, because in the icy mountains a mysterious plane crashes. It turns out that on board is a scientist who set off on a journey to find, before his evil competitor - Dexter, a magical object. This is an ancient figurine, which is the key to the legendary treasury full of gold and precious objects. Unfortunately, Dexter manages to steal the statuette. With the looted treasure, he travels to the Far East to find an ancient chamber in the jungle that can only be opened once every hundred years. At the request of the scientist, the brave Misiek follows in the footsteps of the villain. Reliable lemmings come to the rescue for him, who, at the very thought of adventure, are crazy about happiness. It will be a pursuit full of unusual challenges: aerial acrobatics at the height of a dizzy head, a slalom motorboat on a rapid river and an extremely dangerous run between fancy traps in the middle of the jungle. Polar Bear will get really hot!
