Shrink Ray

The Shrink Ray is one of Dr. Two-Brains's weapons. It is a ray that is capable of shrinking everything.

Its most notable appearance is in the episode "Shrinkin' in the Ray", in which Two-Brains uses it to steal the city's largest cheesecake. He then uses it later on to shrink a giant cheese wheel at the local grocery store and steal it, but with Scoops and The Grocery Store Manager in tow, as they are shrunk, too.

While getting in a skirmish with WordGirl, she as well ends up getting shrunk in the process while trying to prevent Two-Brains from shrinking and stealing the 4:13 Cheese Express, which he does.

A few moments later, at Two-Brains' lair, WordGirl outsmarts Two-Brains and his henchman and is brought back to her normal size shortly after, as is everything else that Two-Brains has stolen. She then fires the shrink ray against Two-Brains and his henchmen, after which she encases them in a jar.
