Requirements & Hints.

Legendary hunters with the O@cean Navigation Kit may hunt mice of the Derr Tribe.

Hunters, only the strongest of physical traps will do here... these mice are feisty fighters! Gouda and SUPERbrie|+ are very acceptable cheeses here, and should earn you the Delicious Stones required to craft the Crunchy Cheese that the tribe leaders prefer here.
Was that a Red pepper seed I saw him drop? Quick plant it and see what happens!
