The Wizard of Oz
1939
Betty falls asleep doing a jigsaw puzzle and finds herself through the looking glass into a modern, urban wonderland. The shrinking potion comes from a "Shrinkola" dispenser. When most of the characters assemble, Betty sings "How Do You Do" to them. But the jabberwock steals Betty away.
