What Happened To Autobunny

@autobunny's real name is Auto Bunny T19. He's our last chance at human survival. His mind is human, taken from a volunteer, his heart is from a very special breed of wild hare who are rumoured to be highly resilient to aging, his body is part mechanical part Crystal and part real bunny.

They brought him back, exactly a year after.. that's about all I'll ever be willing to tell you. All I can show you is this - and you didn't get it from me:
Told you, did'n I. Yup... I wouldn't believe myself too:
This all happened back in '61. Sometimes... sometimes I wonder if autobunny really survived that ordeal...

AutoBunny is very busy in Animal Rescue.
