Megan the Monday Fairy is the 36th book in the mainline Rainbow Magic series, and the 1st in the Fun Day Fairies series.
While Kirsty is staying with Rachel, they meet Francis the frog at the sundial, who assigns them to retrieve the Fun Day Fairies' stolen flags.
Tropes:
- Banister Slide: Some of the goblins are seen sliding down the banisters of the castle due to the influence of the Fun Day flags.
- Hating on Monday: Defied; Megan's flag ensures that Mondays are fun.
- Keet: Having the Fun Day flags around the castle made Jack Frost's goblins too energetic and silly, so he banished them to the human world.
