Puppetoys is a toy company founded by Michael Maddi, a veteran Hollywood special effects artist. He specializes in making Prehistoric Puppets, a line of life-like puppets designed and sculpted using the same methods as film special effects:
The PREHISTORIC PUPPETS line offers six well-known fascinating dinosaurs that are extremely accurate and highly detailed. Our puppets are made from super-soft molded foam that feels very realistic, and has a patent pending process. The unique manufacturing process enables the user’s arm to be supported by the puppets legs while puppeteering. This makes for the most realistic puppets available anywhere! Finally you can really see how these mighty creatures, now long gone, might have looked, moved and fought.
