While the Kratt brothers are being charged by an angry rhino on the African Savanna, they decide to use a harpy eagle feather from Chris's creature souvenir collection to activate Harpy Eagle Powers and fly out of harm's way. However, Chris forgot his souvenir collection on the Arctic tundra during the events of "Baby Tooth and Kid Musky". To find the valuable collection, the Wild Kratts travel to the Arctic and search for the collection using the Creature Powers of the musk ox. However, the team will have to hurry, because Zach Varmitech is also after the creature souvenirs.
