HELP! Golden compass for Wii

[funny_wonder]

Hi, I'm playing the golden compass on wii & Im stuck at one part in the vents. I cant get to the swing at the end, has anyone done this? I've been trying for 3 days & Im getting nowhere. Its just after the bit with Mrs Coulter in the canteen at Bolvangar, Ive turned off the electric grid & made it to the swing at the end but its too far away. Ive tried using pan as a hawk to get the extra distance then changing to sloth but its not working.
