Pianosaurus is Experiment 1163, a green dinosaur with piano keys for teeth. Dr. Sawyer wrote him off as a failure and sent him to testing. In Chapter 4 he charges the Player once, and Doey kills him before he gets there.
The toy
Pianosaurus is a two legged green dinosaur with a long neck and tail. Piano keys run along his underside and form his teeth, and he has coloured horns, spikes and claws.
Experiment 1163
In 'Prisoner Profile, Experiment 1163' Sawyer writes that 1163 shows no human qualities. He snaps at movement, eats anything that fits in his mouth, and cannot play his piano rhythms in tune. Sawyer orders him used for testing, and does not expect him to survive it.
I grow tired of creating mindless invalids. 1160 had his uses, but 1163 lacks the cunning or the size for a similar role.
Use 1163 for testing. If it survives, keep it there. However, I don't expect it to.
The enclosure
The Player crosses a ledge above his enclosure, and the ledge breaks and drops them in. Pianosaurus turns and charges. Stretched dough arms catch him, swing him against the walls and pull him into the dark. His head slides back out. Then Doey steps out and says he has not eaten in weeks.
