His actual name is "Soho-Saurus" and he was manufactured by the "Manhattan Toy Company" for their 2000 line of toys. Unfortunately, Soho-Saurus is currently not in production.
I have searched e-bay and every internet avanue I can think of... I even wrote Manhattan Toys and asked if they had any more hidden away someplace... alas, no. He must be out there someplace.
