Thanks Simon, I was going to try seeing if there were any hidden tunnels (like in GrandDizzy's bit) to fall to the middle pole to get the power cell, but your hint gives me a much better idea ...and I should have thought of that possibility much earlier! Oh, and thanks for nearly giving me a heart attack for when I woke Dozy and had left the hovering platforms in the positions to get the power cell!!!!!!
Annie, I got the carpet from the bottom left sleeping cabin - Dizzy mentions that the carpet isn't stuck down so much ...and think I know where to get a bouncy tile from - so let's grab all those tools and see what damage I can do! Not sure which platforms you mean. If it's the hovering ones in the medic bay, then it was trial and error to try and jump to the first platform and falling into a tunnel.
