Ninja Turtles are back on TV and their toys are hot again: Toys R Us reports that this is another of their most popular items. A towering playset that my younger self would have coveted, the Secret Sewer Lair stands 42 inches tall and has a zip line, a sewer cover that flips down to lower levels, a tire swing, and what appears to be some sort of computer interface, presumably intended for keeping tabs on Shredder and the Foot Clan. Toys R Us has it marked down from $139.99 to $109.99, but it's sold out online, and in-store availability is limited.
