SLEEPY:

Sleepy sneaks in his Z's anytime and anywhere he can, but none of the other dwarfs ever complains. Maybe that's because he works just as hard in their diamond mine as the others, albeit in a more relaxed fashion. In fact, he's so relaxed, and yawns so widely, that the resident housefly keeps buzzing into his mouth in hopes of finding a nice warm home. But even on the perpetual verge of a nap, Sleepy turns out to be twice as observant as his fellows when it most matters. Strangely goaded and prodded by the forest animals outside their mine, none of the dwarfs can figure out what's going on until Sleepy yawns, "Maybe the old Queen's got Snow White." Thanks to Sleepy, the dwarfs are soon off to the rescue.
