Sharp as a pin is the 44th episode in Season 2 of the Danger Mouse (2015 TV Series).
Danger Mouse and Penfold are going to meet Penfold's cousin (coming from New Zealand), called Pinfold. However, Birch Badboy is re-designing all the world's sculptures, and Danger Mouse, being impatient, grabs Pinfold and leaves Penfold! Penfold does whatever he can to catch up, but they are too fast. Can they stop Nelson's Column from being destroyed and destroying the world with earthquakes?
