In this quest file, I discovered a little bug that makes the Fire Boomerang's damage to enemies rather unpredictable. For example, normally, it would take 2 hits with this weapon to kill a blue Leever, but now, it can sometimes kill a blue Leever in one hit. As for enemies that would normally take about 5-10 hits with the fire boomerang to kill, they can sometimes be killed in 2 or 3 hits, or sometimes, even 1 hit.
NOTE: the cheat code is 4. Activate this code, and give Link the Fire Boomerang through Link Data, and try throwing it at various enemies found throughout this quest.
