Dougal and the Blue Cat

Dougal wakes in the magic garden to a rude awakening from his cuckoo clock and recalls a strange event from the previous night. He remembers a red owl and two voices emanating from the old treacle factory, including a female voice repeating 'Blue is beautiful, blue is best. I am blue, I am beautiful, I am best!' He heads to Zebedee for help, pondering what it all could mean.

On the train to Zebedee, Dougal describes the strange night in detail to his friend, detailing the red owl and the strange blue voices. He is briefly interrupted by conversations with Ermintrude, Brian, Dylan, and Mr. MacHenry, but his focus remains on the troubling memory. The retelling sets up the next steps in the mystery.

At Zebedee's roundabout, Zebedee suggests that Florence should be consulted about Dougal's dilemma. Dougal agrees to seek her perspective and help. The plan is to involve Florence to shed light on the blue threat.

Florence arrives at the roundabout, where Mr. Rusty and the other kids introduce her to a sly blue cat named Buxton. Zebedee explains Dougal's trouble, and Florence decides to visit the garden to meet Dougal and Buxton. This meeting marks the beginning of Buxton's influence in the story.

Florence brings Dougal into the garden to meet Buxton, and Dougal immediately feels jealous of the attention the blue cat receives. He becomes wary of Buxton and begins to suspect that the cat is connected to the strange events. The group senses a growing tension around Buxton's arrival.

Buxton begins to plot his takeover, using charm and blue imagery to win the others over while concealing his true intentions. The initial mischief escalates as the blue threat becomes more evident. The garden becomes a focal point for Buxton's plans.

Buxton sneaks away to the treacle factory and meets the Blue Voice, Madam Blue, who plots to turn everything blue and imprison those who are not. In the ruins, Buxton identifies seven doors and is crowned King after correctly naming their blue hues. The power rush signals a turning point in the conflict.

Back in the garden, Dougal warns that Buxton is dangerous, but the others are slow to believe him. Blue cacti start appearing around the garden, and Zebedee arrives claiming his moustache has gone missing. Suspicion rises as the blue influence spreads.

Buxton directs his army to capture everyone, and they are imprisoned in the factory dungeon. Dougal remains free for the moment, watching his friends disappear behind locked doors. The stakes rise as Buxton consolidates power inside the factory.

Dougal disguises himself as Blue Peter by dyeing himself blue and proclaims that he hates sugar. Buxton traps him by locking Dougal in a room full of sugar cubes. The moment tests Dougal's resolve and cunning as he grapples with his identity and the cat's plans.

Dougal endures the sugar torture but refuses to betray his friends. He is released and rewarded with the title of Prime Minister, signaling a clever pivot in the battle against Buxton. The group now has a renewed ally in their struggle.

Dougal tours the caves beneath the treacle factory to locate his friends and succeeds in finding them, though Buxton follows close behind. The escape plan becomes a high-stakes pursuit as they try to outwit Buxton. Tension builds as the group moves toward a final showdown.

Madam Blue orders the conquest of the Moon, promising to paint it blue and conquer the world. The journey to the Moon begins, and during the voyage Dougal falls into a puddle where his blue dye washes away, revealing his true identity. A fight breaks out as the two factions clash across lunar terrain.

Dougal and Buxton battle their forces on the Moon and then return to Earth aboard rockets. Buxton crashes his rocket into the treacle factory, while Dougal parachutes safely back to Earth. Madam Blue's fury erupts upon learning Dougal's true identity and Buxton loses his title in the ensuing chaos.

Back in the magic garden, the group finds a tearful Buxton who expresses remorse. Brian reveals that he is alive and has brought Zebedee's moustache back, restoring the moustache to Zebedee's face. Mr. MacHenry conjures snow and Mr. Rusty takes everyone on a ride on the magic roundabout as they celebrate the return to peace.
