Toonfomercial: Remember Kellogg's Triple Snack cereal? (1964)

 Now, here's an obscurity that came & went during my formative years.

Kellogg's introduced Triple Snack in 1964, but the product, marketed as a cereal, but, as the name suggests, could also be used as a post-meal snack, lasted just 2 years before being pulled from the shelves.

This commercial appears to have been produced by an independent animation house, and not Hanna-Barbera, which had an arrangement with Kellogg's for a few years.
