Mind the Jaws

What I'd love is to get on a deserted tube carriage with one of those cat basket carrier things. An empty one. With the door wide open. Then I'll fall asleep, give it a while, maybe I'll start snoring. Once the tube is packed and on its way, out of nowhere, I'll wake up and start screaming- My snake! My SNAKE!!! Has anyone seen my highly agitated, possibly claustrophobic snake??!
