They have a (unintended) practical use: Cutscene Break
Fun fact: you can use them while bouncing on a Gummi Jump if you use them on the frame you hit the gummi (video). probably in the same vein as Hazard Jump
It is possible to hold more than one pair (found here by thermo):
- open the zoomies box in Sailor Hub
- add a pair with the Cheat Menu
- grab the actual pair
- you now have two pairs (there doesn’t seem to be any effect though)
