You get directions to town (SOUTH along the beach, then follow the path WEST) and head that way. As you walk (rejoined by M. BISON), you scoop up a COCONUT. It shouldn't be that hard to crack it open.
Hmm. It feels... odd. Could something strange be inside this COCONUT? Something stranger than MILK, which, really, what's that doing in there? MILK COMES FROM COWS. OR SUPERMARKETS.
