The three sets were released as 65130 "Toa 3-Pack 2" during 2002.
Turning a gear on Wairuha's lower back causes his legs to move forwards or backwards. This gear function is anchored by a ball joint, providing sturdy poses and preventing Wairuha's legs from slipping when standing.
Wairuha also has two gears on his upper back, each of which can be turned to swing its respective arm.
