Forum member psycho013 spotted this new set, 79122 Shredder’s Lair Rescue, over at ToysRUs.com. It appears to be a new set that was not part of the showroom floor at Toy Fair, so my best guess is that this is an account exclusive. It’s not up on Shop@Home’s website, but it’ll probably go up when all the other March sets go up. Other than ToysRUs stores, you may be able to find it at LEGO Brand Retail locations.
