Evergreen

Synopsis
The story of Evergreen, and his young assistant Gunther, during the prehistoric era, long before the Mushroom War, where they try to avoid a major catastrophe from destroying Earth.

Plot
The episode takes place in the distant past before modern-day Earth and the post Mushroom War Earth. In this time, a young dinosaur named Gunther is playing with his pet dinosaur Nina. He is the badly treated apprentice to a wizard named Evergreen, who Gunther idolizes. Throughout the episode, Gunther's idolization and wish to be like Evergreen is made very clear, which foreshadows the climax of the episode.

After their game he notices the elementals are gathering atop the tower of his master, Urgence Evergreen, and hurries to see the meeting. There, Evergreen meets with a group of elementals. The four elementals are Ice (Evergreen), Candy (Chatsberry), Fire (Balthus) and Slime (Slimy D). They meet to talk about an incoming green meteor set to hit Ooo filled with evil magic. The other elementals do not worry about it, but Evergreen insists that they must act by creating a magical crown that will grant the wearers innermost wish. Evergreen states that he must wear the crown, because his deepest wish is to destroy the comet. The other elementals are against this, as they believe that the crown will corrupt Evergreen. Evergreen then fights the other elementals and ends up freezing them. After the battle, Evergreen summons Gunther, telling them that they will go on a mission to recover the missing piece to his crown.

Evergreen and Gunther then go on a quest where Evergreen rides an ice palanquin and Gunther walks alongside pitifully, being rebuked in his request to ride with Evergreen, an example of the constant abuse Gunther suffers at the hands of Evergreen. Their goal is to get the ruby eyes of the ancient lava dog, Magwood, which will be the source of the magical crown's power. After finding Magwood's lair and successfully fighting to take its eyes to power the crown, our heroes are back at Evergreen's lair. The crown is complete and ready to use. The comet's collision is imminent and Evergreen is about to try to use it to save the world, when Magwood arrives attacking his caste.

The fight renders Evergreen unable to wear the crown and he instructs Gunther to wear the crown while thinking of his deepest wish... to save the world and stop the comet. However, as we have seen throughout the episode, it is clear that Gunther's only wish is to be like his master Evergreen. When he wears the crown, the magic morphs him into a version of Evergreen with similar features like white hair and a long nose (features that are shared with the Ice King.) Gunther's transformation shows the horrible way he is treated by Evergreen, where he shoots ice magic and screams 'Gunther, no!' interminably.

Just as the comet is about to crash, Ice King wakes up and we realize this was a recurring dream that the Ice King has. He wakes up screaming 'Gunther, no!' as Gunther had after his transformation then mimics a large explosion. Ice King then wakes up and sees the penguins Gunthers cowering in fear in the corner where he asks if they have the same recurring dream.

The episode closes with a look into the sky and a far away blue comet hurtling towards Ooo, similar to the green comet had in Ice King's dream.

Episode connections

 * In "What Have You Done?" Ice King mentions that he did not steal the crown, although he did make it with stolen magic. This may be the result of the crown's flashback from Evergreen/Gunter's memories when they steal the magical gems for the crown.
