things could get a little messed up and chunks taken out of him if he's not careful with the queen, even the cave troll could wack him into the ground, i meen when the bullet bounced off his back, it chipped his rock skin, that means these two nasty creatures (if they dont turn on eachother) could mess things up while spiderman swings around saying, " thing be careful, i can't do much if your a bag of sand!"
yeah, he hit a flat surface, then into a pool, so he got it easy from that fall, what if he landed on a sugar load of spikes, just for example, do you think he would just land on them or would they cause some damage to his hide? i think yes, much like the queens, tail, mandibles and claws... and the trolls hammer...?
the troll breaks the aliens neck a bit and gets himself burnt to death from the acid blood.
then thing punches it onto its back spidey resuming its iron - stings it and cuts open its belly - thing throws a rock into its gut were the blood soaks up and dries out - the alien may kill 1 of the heroes but it dies of blood loss
