Whoppers can be found in the lake by area 17 in the Scarlet Forest, specifically above the dam. The term "whopper" refers to various sizable fish, including Gajau, Speartuna, and Great Trevally. To catch a whopper, equip the fishing rod, use the Starduster Rig lure, and follow these steps: pull the rod in the direction the fish swims when it bites, reel it in after it tires, and move the left stick in the direction the fish lands if it jumps. Fishing in open areas free from obstacles is recommended, and using a level one Ranger jewel can help. Successfully catching a whopper rewards players with five gunpowderfish scales, five honey, and 200 Guild Points.
