A seller on eBay had a Cactus Cooler can in his collection and I bought it for $1. I received it today. It's the first "favorite drink of a cartoon character" in my collection.
7-18 Update - I just received some cans from an eBay purchase and it contained an older style of Cactus Cooler. Before becoming part of the Dr Pepper/Snapple Group, it was distributed by Canada Dry.
