The Legend of Zelda: Oracle of Seasons/Golden Monsters

There is said that a mysterious gold-cloaked sage resides somewhere in Holodrum, and has made the monsters appear. He eagerly awaits a person worthy of his treasure, and knows which of his monsters have been slain. If you feel up to his challenge, then it's time to hunt the Golden Beasts!

Golden Beast #1: Golden Moblin
Requirements
 * Obtain the Power of Fall

Head back over to the entrance of Snakes Remains and make it fall. You'll find a Moblin has appeared, except he's gold! He is one of the four Golden Beasts, and is incredibly tough to battle. If you have low-level items, it will be a long, grueling fight.

It will take a lot of sword strikes to defeat him. When you do, he will disappear for good. Now, for the next one!

Golden Beast #2: Golden Octorock
Requirements
 * Obtain the Power of Summer

Enter the far northwestern corner of Spool Swamp to find another Golden Beast, the Golden Moblin. This one will be rather tricky to defeat, because you CANNOT knock it down a hole. Instead, you must tackle it the hard way with your sword. When it's gone, that's too down!
