Cricket Jam

The Cricket Jam is a special item in Super Mario RPG: Legend of the Seven Stars. It is found in Kero Sewers, specifically in a high-placed treasure box that is only reachable via a Warp Pipe. The pipe's other end is located in a cave beneath the Sky Bridge of Land's End. Once Mario obtains the Cricket Jam, he can give it to Frogfucius for ten Frog Coins.
