The Lost Gyro Block is a treasure in Pikmin 2. It is found on the twelfth sublevel of the Hole of Heroes, just before the onslaught of Arachnorb bosses. It is held by an Iridescent Glint Beetle, it will reappear somewhere else in the area if the treasure isn't recovered right away. If the treasure has already been recovered, it will have regular sprays and nectar, but can only be seen once per visit. It is actually a green R.O.B. gyro block.
