Dr. Seuss' Daisy-Head Mayzie was published posthumously after Seuss (Ted Geisel) had passed away. Not only that, but an animated special actually aired before the book was published!
Hanna-Barbera obtained a license to produce the special, which would be the last Seuss book to be adapted for television, and H-B's only Seuss special. Tim Curry (The Wild Thornberrys) is among the voices heard in the special. Regrettably, the complete show isn't available on YouTube or Dailymotion. For now, let's serve up a little commercial "trailer" TNT produced.......
The Cat in the Hat, essentially Seuss' mascot, serves as narrator, and this would be his last animated appearance until PBS' The Cat In The Hat Knows a Lot About That. Mayzie is your average, ordinary schoolgirl until a daisy sprouts up on her head. No one seems to know why or how, but there's something to this that makes this as much a teaching tool as a form of entertainment.
