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).
Danger Mouse and Penfold are in a training simulation when one of DM's flying kicks damages the holodeck with catastrophic consequences. They wake to find they've been in a three-year dream, that they aren't secret agents and work in IT instead, and the Danger Agency has been a figment of their imaginations! Whilst Penfold and Squawk quickly settle into a life of menial office work, DM struggles to accept life as Dane G Mouse.
There's relief all around when Penfold's pilfering of Squawk's gadgets and clandestine late night trips to shady warehouses turns out to preparation for his taking part in 'bot battles' - a fight club for homemade robots. Penfold hopes to enter his own creation, Geoff, into the competition but is sidelined by an overeager Danger Mouse and his own robot, the CRN 3000! When the CRN 3000 obliterates all challengers, DM's call for a worthy opponent is answered by Megahurtz. But Megahurtz may have a secret android army agenda...
Danger Mouse's over-reliance on gadgets prompts Colonel K to send his top agent on a tech-free nature retreat. Unbeknownst to Danger Mouse, Greenback has the same plans for his daughter, Delilah, whose social media obsession has also spiralled out of control. Back at HQ Penfold is tasked with protecting the entire world from the threat of super-villainy. Stripped off his gadgets, DM struggles to adapt to life in the wilderness and, when a talking pine cone called Conni begins to offer him survival tips, he begins to question his own sanity. Soon enough, Delilah catches wind of DM's presence and she plots to destroy him as a means of getting back into her Dad's good books.
A mishap on a mission leaves Danger Mouse confused - why is Penfold not talking to him? It might be because today is Penfold's birthday and he hasn't remembered it again! Squawk sprays DM with her experimental empathy gas in the hope that he will find it easier to care about other people. The newly empathetic DM is a changed mouse! One who seems to think breaking the Baron out of prison is a great idea.
Baron Greenback brews a plot to steal every beverage on the planet, mix them all together, making an un-drinkable disgusting sludge. By depriving the population of their much-needed drinks break he'll cause worldwide exhaustion. Danger Mouse seems unfazed, but without his cherished tea Penfold wilts on their rescue mission. Can Danger Mouse thwart the Baron's thirsty plot?
Danger Mouse and Penfold are celebrating another noisy victory, gleefully ringing Big Ben's bell when an over-excited Penfold falls, pushing the clock hand forward, causing the sun to go down prematurely. Unbeknownst to them a mysterious figure watches on from nearby noting the clock's incredible time-controlling powers. When DM realises that the day is being stolen and replaced with a silent night, he enlists the help of expert colleagues - the night shift! With Danger Moth and Danger Mole in tow the team track the quiet culprit. But a noisy Danger Mouse might just be outwitted by this stealthy saboteur.
The danger agents are at Squawk's super-secret Wild West testing facility, home to a society of Penbots, robots who have a rather familiar face. Squawk is sure she's improved upon Penfold and made the perfect robotic sidekick for Danger Mouse, Tenfold. But Tenfold malfunctions and transforms into the ruthless Meanfold, determined to destroy anyone who's not quite perfect.
It's a special festive episode of the Jimmy Camel Show: "The Danger Mouse Celebration Episode." Danger Mouse and Penfold are on the guest sofa, but Penfold is suspicious. Shouldn't they be doing something else right now? Jimmy shows them clips from previous episodes, focusing on DM's recklessness and Penfold's uselessness. Is Jimmy going to drive a wedge between them? It certainly seems that way...
Colonel K spins a terrifying tale about the Headless Postman - an ancient and alarmingly scary apparition. When the haunting figure of the postman suddenly appears, petrified panic reigns supreme amongst the Danger Agents, until Squawkencluck reveals herself as the postman in disguise and that the whole scenario has been a company-mandated bravery test. By remaining characteristically unfazed throughout, Danger Mouse fails the exam, which puts his job at risk, as in Squawk's words 'being truly brave means being afraid of something and still taking it on'. The gang try to scare DM, but he's fearless... until he discovers that the Headless Postman lives!
When Colonel K disappears on a free holiday, Danger Mouse pulls rank and assumes the mantle of caretaker Colonel. However, the role is much less exciting than he anticipated, as world-saving missions make way for endless paperwork. Meanwhile, K's freebie spa retreat happens to be a diversion tactic in Greenback's latest plot to take over the world, with the Baron banking on the Danger Agency falling apart without its figurehead and the world descending into disarray.
Playtime is over as Danger Mouse battles an army of vengeful soft toys. Pink Dawn's henchman teddy bear Snuggles is on an angry rampage. He is zapping cuddly toys, bringing them to life as rage-filled criminals. He will annihilate anyone who refuses to be his friend. Danger Mouse spots the source of Snuggles power - Pink Dawn's tiara! When Penfold's beloved teddy, Bernard, rejects his owner to join Snuggles's new gang, Danger Mouse and the distraught Penfold rush to confront Dawn. They are shocked to discover that Dawn has ditched pink in favour of a super-powered goth darkness. Can DM reunite Dawn and Snuggles and put a stop to this rampage? Will Bernard ever return to the ever-loving Penfold?
