i got 4 and used them now i have one, the chest left in the other island beside the gate where the jaguar is
That half case wasn't 20th. The 20th case is under trees if you walk down to south from the Jaguar--your left hand beside cliff. Not sure if you have found a key in the Beach
may you please email me the exact place of the key on juve-2006@hotmail.com ?
