Episode Title:
Penfold Transformed!.
Episode Description:
Dr Crumhorn holds Penfold captive and has created a robot duplicate of him (which is far more efficient than the original). At the push of a button, it transforms into a giant machine intent on destroying Danger Mouse and his pillar box. Meanwhile, envious of Crumhorn's own plan, Greenback has Stiletto disguised as Penfold in costume in his attempt to hack into Danger Mouse's pillar box.
