Grizzy & the Lemmings (2016)

S2E9 Call of the Bear

Grizzy and the Lemmings stumble upon a box filled with whistles at the cabin, which have the power to draw in various creatures that respond to the one whistling. Eager to take advantage of this discovery, both Grizzy and the Lemmings set their sights on luring a group of partridges.
