Hmmm. Twinmold? Oh yeah. He was fun. Just use the Gient's Mask you got in the temple and slash at his/her head and tail with your sword. Or you can stand on the platform and shoot it with fire, ice, or light arrows. But that's harder. And the other way is better in my opinion. All the best
You're so lucky. I don't get a break from my school until the end of March.... Oh well. What Zelda game are you playing right now? I just beat Majora's Mask for the second time.
