go far left until you see poliwrath.capture it.use its field move on steelix until it
moves.hope this helps

\nasdfhnx.-

capture a snezel it worked for me when i had Ranger

capture sneezel than vs steelix use sneezel as pokeasit than it will extend the capture
line than circle him trust me it works (i figured it out)

When its head touches its tail shoot a bubble with poliwraths poké assist and you've got
it.
