One! Two-hoo! Three! *crunch* "Three."
The famous "how many licks does it take to get to the Tootsie-Roll center of a Toostie Pop" commercial was created in 1968, but didn't really begin being seen until 1970; that means Tootsie Pops have been advertised the exact same way* for 50 solid years! Same animation, same voiceover, same everything. Can any other product claim the same thing? It's nearly unthinkable!
The association of owls with brains is a holdover from the ancient Greeks, where the owl was the symbol of Athena, goddess of wisdom (and that connection was because so many little owls hung around the Parthenon, the main temple dedicated to her). Mr. Owl further displays his smarts by wearing glasses and a graduate's mortarboard.
If you watch the Tootsie Pop ad, Mr. Owl is pure white; the backgrounds are colorful, but all the characters are simply black outlines around blank spaces. That wouldn't make for a very interesting toy, so this Mystery Mini gives him orange for his feet and beak, and blue for his glasses. Unlike the POP! version of Mr. Owl, this one is holding the Tootsie Pop in the right hand; unlike the POP! version, the candy is red instead of the proper yellow. Eh, it makes for better contrast. Change approved! If you turn the toy around, you'll even get to see his little tail feathers.
If you've ever made it to the center of a Tootsie Pop without biting, you can download a certificate celebrating your achievement. Mr. Owl has "signed" it with his footprints, though whoever designed it didn't bother to consider either what the cartoon's feet look like, or what a real owl's feet look like. Whoops!
