Zebra is putting on a production of the alphabet. Everything is going just fine ("A is for Apple/B is for Ball/C is for Cat") when suddenly Moose breaks in -- "D is for Moose." Moose keeps asking if it's his turn through E, F, G, H, I, J, and K. Anticipation builds on L, and then... "M is for Mouse." Moose goes ballistic, completely wrecking the set for N, O, P, and Q. Just like Melanie Watt's Chester, Moose takes his red crayon to R and S, and then Zebra protects T-Y with his life.
