I used to collect Lisa Frank EXTENSIVELY as a child, and I remember looking at the flyers that came with the magazine for the cuddle buddies. They had the unicorns, horses, dolphins, puppies, kittens, etc, but I never saw an alien cuddle buddy. The best they can do is scour sites like ebay, etsy, or facebook pages daily to see what’s new! I’m sorry I couldn’t be of more help. I will post this publicly so my followers can contact you if they know anything else! My guess is that they’re extremely rare and tough to find, as is most of the Lisa Frank alien merchandise. Best of luck.
