Your armor protects you

As the swarm of asses pummels you, your armor makes sure you stay intact. Eventually, one of the butts pushes you a little weird, and you fall through the bars of the mob spawner. Looking up, you see the skeletons slamming their asses down, seemingly not noticing your absence. You use this opportunity to run to the chest and take it's contents. Looking through, you find some crafting resources, a few blocks, and more than enough iron to forge a full set of tools. You make a hasty retreat, and head down the other path the cave provided to you.
