Dastardly Danny, along with the rest of the Mud Dogs, was arrested for an unknown crime. When Raph was put in the jail after being mistaken for Heinous Green, Dastardly Danny decides to make him the leader of their group, much to Loathsome Leonard's disappointment.
After being escaped, Raph tries to get the criminals back to jail, but every plan he made worked, ending up in further success for the Mud Dogs. They decide to take him to Big Mama, who explains that Raph isn't Heinous Green, he stands over there.
Dastardly Danny, along with Loathsome Leonard and Malicious Mickey, became angered and infuriated by Raph lying to him. They attempt to kill him, but they bump into Big Mama, leaving Raph to deal with Heinous Green.
It is unknown what happened to Dastardly Danny, but Raph reported his activities to the Hidden City Police before Raph himself was again detained.
