Ernest Penfold is DM's assistant/best friend. Often mistaken for a mole (presumably on account of his spectacles), Penfold is actually a hamster. He is codenamed the Jigsaw because, at the first sign of danger, he falls to pieces.
↑ Made from recycled Melon fibres.
↑ He has a severe allergy to them, which causes them to swell up.
 ↑ Co-creator
Brian Cosgrove has confirmed this on at least one occasion. Penfold describes himself as a hamster in  Danger at C Level, the second episode of the rebooted series.
