NEED HELP?HERE IT IS!
I found this one surfing on the web.
Once u have the bombrang go to hyruel castle.
Go to the tree.This cant be done if u have already got the gold
scltulla.Go in,find the gold scltulla,kill it and throw ur bombrang at the token.
Before it gets back to u when u throw ur bombrang run to the exit and u do this as many times as u want.
I haven't tryed it but it might work.If u want to know
the tree is by where u found Malon sleeping,should be easy to find.
