Just Him?

Leonel landed on the coy fish, exhaling a long breath. At the same time, a bit of fear couldn't help but creep into his heart as well as a bit of anticipation. This coy fish's ability was really too sinister. If he had been fighting alone, it could be said that he would have had a much harder time even if it ended in his victory. As for why he was filled with anticipation, it was of course because if he could refine the ability into a treasure, the potential applications were tantalizing. 

Leonel most wanted this ability for its application in escape. He could tell that the coy fish wasn't creating water, but was instead transforming earth into water. If this was a treasure instead of an ability and it was tweaked a bit, wouldn't it be possible to escape through the ground?
