As our protagonists rather unusual pet, I decided to post a little informative chapter on the reptile.
Basically a chapter with racts on Rex-y noodle.
They grow up to an average of 55cm.
Rex is currently about 45cm and around three years old.
He's male so he has a grey-ish colouring.
These snakes generally live up to 10-15 years and weigh around 50-180g
Yes they are venomous, but Alex is a parselmouth. So I suppose it balances out.
