The Ruby Pipe is treasure that can be obtained in Sly Cooper: Age of Thieves in the episode Alice in Cooperland. It is worth 234 coins and the allotted time players have to get it to the safehouse is forty-three seconds.
"Feast your eyes on the Ruby Pipe! This is the first pipe to blow bubbles, making it safe to use. Just make sure to keep it far away from children, though, as they could get the wrong idea. Regardless, this valuable pipe was said to have been invented by Thaddeus Winslow Cooper I and II, and is truly the only one of its kind."
It is located in a tunnel underneath the Caterpillar Statues in the northernmost section of Wonderland. Only Sly's Buccaneer Costume can be used to access this treasure.
