Security Safe

The Security Safe is a treasure from Pikmin 4:Pikmin Adventure. It is found in Long Legs Hole after defeating the Giant Beadypuffleg on the last sublevel. It is actually a lock for things like suitcases.

Olimar's Notes
This treasure apparently was used by an ancient civilization to capture criminals, but could it be used to do other things?

Sales Pitch
This treasure was used a long time ago to lock up baddies! Can you figure out another way to use it?
