[Peter doesn't waste any time following that order, nimbly leaping from the creature's back and sticking to a nearby wall. Once he's safely out of trampling range and making sure that Tinya isn't in the middle of the trample zone, he uses his webs to pull a big chunk of rubble down on the critter's head. Ker-smoosh!]

So, turns out, these things are really hard to steer. Or maybe I just have no idea what I'm doing, its probably that.
