S2·E63 Zero Visibility

Grizzy is captivated by a mime artist on TV who makes viewers believe in the presence of an invisible wall; to get rid of the Lemmings who have their sights set on the jar of Yummy XL chocolate spread, Grizzy hides it and pretends it's invisible. After making them fools, Lemmings also tried a fake magic incidence and snatch the Yummy XL. During fighting, Grizzy accidentally falls underground hill and found a magical leaf that could make anything real but invisible.
