At Cape Claw, when Fox first talks to the HighTop, he tells Fox that he buried his Gold Bars in the sand to hide them from the SharpClaws. However, the HighTop forgot the locations of all four Gold Bars, so he tasks Fox to find them. Fox managed to uncover all four by having Prince Tricky use his Find Command to dig through each of the four dirt patches. After retrieving every Gold Bar, Fox and Tricky returned them to the HighTop. As a reward, the HighTop allows Fox to access the Gas Trap beside the Ocean Force Point Temple.
