BartlebyA show trialThe ruby mine
Bartleby the Prisoner is episode 37 of Sonic Underground, DiC’s 1999 cartoon about Sonic, Sonia and Manic, the hedgehog triplets of Queen Aleena. It is number 37 in production order – the order TF1 first showed the series in France, where it premiered on 12 May 1999 – and it was the 37th episode to air in the United States, on 19 October 1999. It was written by Elenor Burian-Mohr and Terence Taylor, and its song is “Justice Calling”.
Synopsis

Bartleby, the mink Sonia was once meant to marry, finally gets his hero moment. Robotnik has him charged with treason and convicted in a show trial – a trial that is really bait for Sonia and her brothers. When Bartleby works that out, he would rather be roboticized than see her caught, and begs her to stay away.
Sonia cannot stay away, but first there is a job to do. The siblings have orders to blow up a ruby mine whose stones are good enough to drive titanium-cutting lasers.
With the mine in pieces, Sonia races to the rescue, but Sonic’s speed gets him and Manic there first, and they spring Bartleby from his cell. He and Sonia say goodbye at an airport, and the pompous mink leaves as one of the show’s real heroes.
The Song: “Justice Calling”
“Justice Calling” suits an episode built around a rigged trial.
