The Laser Toothbrush is an item seen in SPY Fox in "Dry Cereal".
Monkey Penny gives this toothbrush and drachmas to SPY Fox for his mission on finding Mr. Udderly. SPY Fox mistakens it for a regular toothbrush until Monkey Penny warns him to not put it in his mouth and explains what it really is. She then explains that the toothbrush can be used to cut through thick steel after applying the minty fresh laser gel on it and pressing the button.
When SPY Fox goes to the Fetta Factory, he uses the Laser Toothbrush to create a fox-shaped entrance in the steel door. Shortly after creating the fox shape, the toothbrush explodes in SPY Fox's hand. SPY Fox then snaps his fingers and the door parts that he cut up fall off of the door.
