I'm in the scrapyard and not sure what to do. I can put hoverboard over the poison lake, but then I don't know how to propel it (and there aren't any assholes with other hotherboards nearby :) Rooter with his rear jet could be helpful, but he won't climb on hoverboard and I don't know how to utilize his thruster otherwise. I tried taking Roouter's head with me, but it is not possible to "lasso" the ladder.
I assume I need a metal rod to use as an oar, or the like, but I can't get that either. I have Rooter's head, but Ace "has no clear shot".
