I had a bunch, but you knew that. Pythons, Iguanas, monitors, random smaller things. I had a rattler once, till I realised I could die, and took him back where I got him (this was less than 12 hours, and never left the vacinity of the collection. I'll call it a dumbfounding burst of youthfull stupidity.)
I have two fish right now.
I did get a robo raptor for christmas, and when the tempermental bastard wants to work, he as cool as most of the real reptiles I've had. Those things are seriously neat wiht the different moods you can put them in for interaction. My four year old won't go near him in "Hunting Mood".
The best part of a robo raptor over any of the real reptiles???
It does not poop.
My pythons would wake me up out of a dead sleep when they dropped the bomb.
