Escaped, But How?

We had just gotten in our reptile shipment.
-Well, they had come in a little bit ago.
But I'd finally found a moment to finally put our newest reptiles away into their cages.

And as I was pulling out our new ball python -who was huge. About two times the size of the ones we usually get in.
I had a mother and her two kids come by.
Oooing and awwwing that I had a snake in my hands.
To which I showed it to them closer.
Before placing him in his cage.

-I'd had to play a little bit of ring around the rosie, because our ball pythons usually come in smaller, so they're fine being in our smaller cages.
But this new snake...was huge.
So I had to move one of our other snakes from it's medium sized cage into a smaller cage so I could put the larger snake in the larger cage.

Easy peasy.

Until I tried to move the cage back into it's position so I could lock it up again.
I pushed,
And it felt like I was encountering something squishy.
Which was weird....there shouldn't be anything rubbery/squishy behind that tank.
I mean I had just pulled it out two minutes ago.

Confused,
I pulled the cage out and to my surprise.
Discovered that somehow.
Our other ball python had escaped it's cage!!!
And was currently resting behind the new ball python's cage.

How?!
HOW!!
How did it get out?!

AHHHH!!!

I mean that snake is also larger, so it hardly makes sense that he'd somehow be able to squeeze through a small space to get out.

Granted...the cage he was in...the lid is easy to take off.
But considering the snake had been in that cage for a week already....without escaping...
Made the fact that it had escaped now all the more surprising.

*shakes head*
I couldn't have him doing that again.
So I had to play ring around the rosie with this snake as well in order to get him into a cage that I hope he won't escape from.

All while the customers were watching. lol.
At least this group didn't freak out when they saw the snake had gotten loose.....
