One of the amusing Betty Boop black-and-white cartoon shorts from Fleischer Studios, "Betty in Blunderland" (reusing the "Blunderland" title from "Felix the Cat in Blunderland" (1926), which I have unfortunately been unable to see as of yet) crams as many references to Lewis Carroll's Alice books as it can in under seven minutes while all the while Betty sings "How Do You Do" to the books' cast of characters. Being Betty, this is also remarkable for introducing sexual humor to the famous children's narrative, including her skirt flying up as she falls down the rabbit hole.
Her Wonderland, or "Blunderland," adventure is framed, as per the books, as a dream--here, after she falls asleep working on a Wonderland jigsaw puzzle of Alice and the White Rabbit (a mise-en-abyme). The White Rabbit rises from the puzzle and enters Wonderland through the looking glass, with Betty in her dream state following suit. No time is wasted on Betty, like Alice, finding her surroundings confusing. Her passage to the dreamscape's populace is streamlined by a subway station through the rabbit hole and a cat serving as soda jerk for "Shrink-ola" to get through the tiny door. When the Jabberwock shows up and captures Betty, her adventure is soon over as the rest of Wonderland's inhabitants come to her rescue.
