After he passed, his esophagus was distended, and I could see the obstruction. I actually removed it with tweezers to see what killed him, and it was just a huge clump of coconut fiber, and it stank horribly, I almost threw up. I picked it apart with a small knife and it was just dirt, nothing unusual at all. I never used gravel or moss in his terrarium.

I have to conclude with the extreme unlikeliness of this whole thing to everyone else that this was some sort of freak accident that took out poor Escobar. I'm going to be very careful with how his little successor gets fed until he's pretty sizable, just to be on the safe side.
