A double-length musical special. Danger Mouse reluctantly takes part in Pink Dawn's re-enactment of Melted, a famous ice-themed musical phenomenon. Penfold is delighted by the prospect of a starring role, but Danger Mouse struggles to hide his disdain for singing, even though by agreeing to take part in the fantasy re-enactment he might just stop Dawn melting the North Pole and flooding the world. Whilst the world starts to get a bit soggy, DM has to rely on Penfold and Professor Squawkencluck's encyclopaedic knowledge of Melted in order to keep up with Dawn and her efforts to dramatise every plot point. Featuring the voices of Alexander Armstrong (Danger Mouse), Kevin Eldon (Penfold), Morwenna Banks (Pink Dawn/Computer Voice), Dave Lamb (Narrator), Shauna MacDonald (Professor Squawkencluck), Stephen Fry (Colonel K), Ed Gaughan (Mr Snuggles) and Kayvan Novak (King Kong Brunel).

An accidental sidekick swap leaves Danger Mouse with Pinfold, Penfold’s cousin.
