I found them at one of the Mayan temples (forget the names). One had the red howler monkeys and the other had black jaguars.
I'm sorry but every time I hear stuff like red howler monkeys or black jaguars I can't help but think of Omecs Temple! lol --- ~Remember, if a stranger offers you candy, take it. It could be the last piece you get!!!~ GT: Xbox: Undying Will31 / PSN: Krilgeta
