Wheatley lets out a whoop as Mars plummets back down, yelling excitedly "Did you see 'em? Did you? Fantastic! Now just-- oh wait, there he goes again." Annnd as he falls he'll hit the rubber once more and then... bounce again. Once more, make a jump check. Below 10 hits the ceiling, 15 or below goes back up through the hole after they get a few comments in, and 16+ allows him to steer his landing so that he doesn't actually fall onto the goo and stays on the ground.
