The Biggs' Toys was a shop selling toys on Miri's planet.
It had been in operation in the 1960s when almost the planet's entire population was wiped out. The building was still standing when a USS Enterprise landing party arrived in 2266.
The Onlies hid from the crew of the USS Enterprise in Biggs' Toys. James T. Kirk initially confronted the Onlies in Biggs' Toys, where he was attacked by Louise. (TOS: "Miri")
