Okay, so recently I've seen this thing on my boys head.. I don't know what's up with it. Since I'm still a new snake owner. Is it something to worry about?

Between his eyes ontop of his head is where it is. There's another small spot a bit further down on his right side. I hope you can see it.

It hasnt been there before.

My suspicion:

I have the exo terra 90x30x45, and as many of you know, it comes with a styrofoam back board.
The backboard has a little hole-ish thing on the bottom and top to run and hide wires in.

Now a few days ago, I caught him trying to squeeze into that little hole.. I pulled the board up and took his head out of it carefully (cant rememebr if the spot was there already or not) I then placed one of his houses back infront of it, hoping that he'll not try it again.

I was wrong. the next day, I came upstairs after being at the vet with my bunny for shots and I heard a very familiar cracky sound. the sound of the styrofoam rubbing against the glass.. I go over to the cage and found the backboard far apart from the back of the cage and my boy bucky sqished behind it..

I opened the screen top and he slid out. that;s when I noticed the mark on his head but I cant be too sure if it's actually from there.
The reason for him roaming a round a lot lately, might be due to the fact that he hasn't eaten in a couple of weeks, since I'm trying to convert him to F/T
