Mechanical Skeleton
From Jenny Everywhere Wiki
The Mechanical Skeleton was a huge skeleton-like construct animated by clockwork, and one of the final guardians of the exit of Madame Tarsa's Toybox, residing in the Doom Room.
During Larrikin-1029 and Pessimist-242's adventure through the Toybox, the Skeleton managed to swallow Pessimist, who ended up trapped in its ribcage. However, there, Pessimist realised he could mess with the Skeleton's gears; identifying the master-gear from which all the others drew their power, he dislodged it, causing the Skeleton to tip over and crumble.
