when you have the bunny hood and you're in 
east clock town, go to were the bomber is 
that you have to give the password to. When
you're next to him turn right and put your 
bunny hood and run to the ledge and jump 
over the big gap (under the guard) and then 
jump over and land in the basket. Then jump 
to the other ledge and walk and you will 
see a chest. IT HAS 100 rupies in it. Then
restart you game and you can do it again and
again etc.
