You were chasing after The Chameleon after he decided to rob some pretty expensive jewelry all because he couldn't afford said jewelry at the Petropolis Jewelry store. While you proceed to run after him, he transforms into a "WET FLOOR" sign and positions himself next to a small puddle of water, with the jewelry hanging on the sign.

"Well, if there's one thing people are less likely to pay attention to, it would be a wet floor. And believe me, it has always been a recipe for disaster! Uh......don't ask how I know that!"
