In the first part of the book, Dopey heads home from the mine with the rest of the dwarfs. After dinner, he blows soap bubbles out of his ears and makes music with his drumsticks.
He then takes center stage dancing while the others play the instruments.
That evening, he falls asleep on a bench, curled up with a bunny. In the morning, he jumps up to start cleaning with a feather duster but ends up chasing a loose feather all over the room. The dust causes Sneezy to explode with a big sneeze--so big that it blows Dopey up the chimney and onto a tree branch.
