My sister is on a "Chip 'n Dale Rescue Rangers" kick, and she bought a Rescue Rangers Lite Brite refill set on eBay, along with a vintage Lite Brite (we are a die hard collector's worst nightmare). Actually, the Rescue Rangers set is used, according to mein sister, and she got it in a lot with a DuckTales set (yay me!) so I went and found two sets of my own: My Little Pony (1980's), and "Fraggle Rock." The only problem is the Fraggle Rock set is incomplete, but I don't know what sheets are missing (one is Gobo, I know that), but the set has two Wembley's included, so that makes me happy at least. The My Little Pony one is complete, though.
