Dual Wheeler

The Dual Wheeler is a treasure found in. It is actually a pair of glasses.

Collecting the treasure
After the cutscene where two Pikmin fight over a Sparklium Seed, a large vine leads upwards to two small alcoves. The treasure can be found past a doorway on the left. In the room where the treasure is, there are two sets of elevator platforms: one red and one yellow. First climb onto the lower platform of the red set and raise it up. Then move to the lower of the yellow set and raise that platform. After that platform has been raised, walk off it onto the newly lowered one, and raise that up, similar in manner to collecting the Massage Girdle. Once that platform has been raised, the treasure is collected by simply walking right.
