My Son...

In case you miss it with the rapid respond of all the mobs around here, he's hanging out behind a shell, completely safe.

Don't be a dummy like me... I was waiting for him to "respawn" in front of the two shells... I waited for maybe 5-10 minutes...

then I took a peak around the back of one of the shells... sure enough there he was.
