The spider-eating guy

[gandalf91]

That's plausible but I highly doubt it for multiple reasons:

Spoiler below!

- The worms seem to be a bit deeper in the mine
- They are a bit bigger than that (though size deviation is arguable, especially among young or such)
- You don't feel any rumbling or hear any worm noises
- The letter in the kennel mentions Wilbur sneaking back out into the mine periodically, tunneling through walls, etc.

Well whatever it was it didn't seem very human to me.

And the tunnel dwelling dude in the kennel did........?

LOL
