Go to the final battle and use the frosty rang on all the canons but
don't do them all at the same time because you have to bite them as well
when they have got the ice on. then use the flamerang on the door with a
x on then go into the room and use your rang on all the big tubes then
sly will give you the doomarang. Use the doomarang and control it to
where the head was. There will be a maze and you have to control the
doomarang through the maze. When you get to where there is 2 tubes 1
going left and one going right go for the one going right.
