Wonderflonium is an exotic material required for Dr. Horrible's freeze ray.
Bouncing it is not encouraged, although the effects of doing this are unknown.


  • It was is presumed that it was used in Dr. Horrible's Death Ray, which caused the weapon to explode after bouncing on the ground.
    • Maybe the reason it failed after hitting the ground was actual physical damage to the device itself, not related to Wonderflonium.
