The Snooze Ray is Dr. Two Brains's weapon. It is used to put others to sleep. Its first appearance was in "Showdown at the Secret Spaceship Hideout", when it backfired on Two-Brains. In the climax, Two-Brains threatened to use it and make WordGirl sleep forever. However, WordGirl managed to distract Two-Brains long enough to capture him and prevent him from using the ray.
