What a suntabulous bicuspid of a day! It's time for the Sunshine Smile Hour, a dental hygiene-themed children's program! Oh golly, this is a good one, and ain't that the tooth.
So this episode is utterly wackadoo: imagine a musical comedy along the lines of Book of Mormon, Avenue Q, or Reefer Madness, with a solid helping of noir pastiche and cosmic horror alongside. The Fall of the House of Sunshine is like if you put all of the above musicals into a high-powered blender along with a collection of H.P. Lovecraft short stories, a pint of ether and a handful of dexedrine. It is hilarious! It is offensive! It is stylistically all over the place! It is RELENTLESS!
