Dingbot Prime

Dingbot Prime is Agatha's second working clank (after the Search Engine) and the primogenitor of many of the latter Dingbots. He came with Agatha when she escaped from Castle Wulfenbach and continued to build while Agatha traveled with the Circus. While in Sturmhalten, Agatha modified him to produce dingbots that could make her music. It was Dingbot Prime who turned on Agatha's singal device, which is where he was last seen. Even though he wasn't obviously brought with to Mechanicsburg, he's been known to stow away in the oddest places, so it's not too surprising that he's since shown up.
