The celebration Fraggles are modeled after their radish festival costumes and the winter outfits from the Bells of Fraggle Rock. Just a quick idea from the given list. This has a pseudo-even spacing and each wave is a little bit stronger. I don't see any Fraggle figure series lasting longer than 2 years so I only listed 8 waves and 4 playsets.
