How to get the third spy on Spy Island

You must get to the rooftops with the BOWTIE, being careful to STAY ON THE WINDOW SILLS.
Once you get up there, go to the platform UNDER THE ONE WITH B.A.D. DUDE. Using the BOWTIE,
GRAPPLE TO THE BUILDING THAT HAS THE BIG ANTENNA TO THE LEFT OF IT(the building is towards
the left of where you should be standing). Climb to the top of the antenna (yes, you will
need the bowtie again). Go to the right of the part that is sticking up from where you are
standing. If you don't, you will end up grappling to the thing. Anyway, grapple to the thin
antenna that is to the right of you, then jump. Go to the right until you get to the place
where you can enter.
Once you get inside, go to the cherry bomb tree on the FAR RIGHT. Push it to the flower on
the ground so it can bounce up two levels. Then, go to the right of the cherry bomb tree and
grapple yourself to the level right above you. Push it over so that it falls onto the second
level. Go don with it and push it over so that it bounces up on the flower. Go up to the top
level so that you end up to the left of the bomb and push it over to in front of the cage
that the lady is in. After it explodes, it will blow up the cage so she can walk out. if you
are unable to get it over in time, the tree will grow another bomb.
