XD Nice.. This is similar to something that happened to me. I ran outside.. Saw a creeper.. Killed him... then 7 of his friends followed me back to my home, I ended up getting a crap load of sulphur.
Anyway, Judging by the inventory of the comic guy, Im assuming he.. Chopped some trees, killed a sheep, dug 3 down into the ground to get a bunch of cobblestone, built a cobblestone house, Wala your inventory?
