Griffin was a collector from the Needle.
Griffin's collection of creatures included Mandelbrots, a Dodo, bog wraiths, Serpentoidians, Hypnoredips, a robo-destroyer, a leopard woman, a man with three eyes and Mutant Marvin the Two-Horned Unicorn.
Griffin travelled to San Francisco in 2002, where he attempted to collect creatures that were falling through a dimensional scar. Griffin was stopped from capturing the creatures by the Eighth Doctor, who pushed Griffin into the dimensional scar. (PROSE: Unnatural History)
