Cap'n Crunch (commercial, 1969)

A mysterious island. Where? Uh, where? Oh, there. Good idea. A careful crew. But this knows what we'll find on this island. Goodness is right, Captain. Just taste these red berries. Why? They're crunchy. They taste like strawberries.

But they're crunchy. Crew, we've discovered Crunchberry Island. Oh, just wait till I tell the folks at Quaker. Well, I did tell them. And now, besides regular Captain Crunch, there's a brand new cereal called Captain Crunch with Crunchberries.

Sweet and tasty like regular Captain Crunch, but with genuine crunchberries in it. They taste like strawberries. Let's hear it for new Captain Crunch with Crunchberries. A hearty cheer was more what I had in mind.
