Unfortunately there was never any Stretch Monster Crunch cereal or for that matter not even a mini-Stretch Monster free in every box type of premium. The closest thing I could tie a connection between Stretch Monster and cereal is this old Cheerios box.
I refer to this 1978 box as the 2-Sided Star Wars Poster & Kenner Refund Box.
Naturally, General Mills offered many Star Wars premiums in their many brands of cereal since Kenner Toys, then owned by the Big G, was producing all the Star Wars toys.
As you can see I only colored Vader’s lightsaber. I’m sure I was too anxious to hang it on the wall and decided to forget about coloring. Hey, I had plenty of coloring books to color and I didn’t have any works of art with a Star Destroyer hanging on my wall.
