Revenge of the Rainbow Dragons is the sixth book in the Endless Quest Gamebook series, and the sequel to an earlier book, Pillars of Pentegarn.
Jaimie's been adopted by Pentegarn from the last book and is now a sorcerer's apprentice. Some other wizards claim dominion over his territory, and he goes to settle the matter with them. While the adults are busy, Jaimie and his animal sidekicks are shunted off on an adventure of their own, possibly encountering the rainbow dragons who once ruled the kingdom.
Probably most notable to a modern audience for how it was the subject of a series of YouTube videos by ProJared for his D&December segments, who let his followers vote on what they should do at each juncture.
Revenge of the Rainbow Dragons provides examples of:
- Animated Armor: One hazard in the wizards' castle is a room full of empty, but very lively, suits of armor.
- The Apprentice: Jaimie's started learning magic under Pentegarn since their victory in the last book.
- Big, Thin, Short Trio: The coalition of evil wizards is mostly differentiated through their body types, matching this.
- Bratty Half-Pint: Princess Imogene, who kicks shins, destroys dolls, and complains that she isn't being properly rescued when Jaimie and his friends find her.
- Chuck Cunningham Syndrome: There's no mention at all of the two adventurers who helped Pentegarn on the previous book's quest.
- Cutting Off the Branches: Pentegarn's path through the first book seems to be regarded as canon, with how he's mentioned having the magic artifacts found in that path two or three times in this sequel.
- Evil Sorcerer: The three wizards who challenge Pentegarn, and are none too subtle about what they're really like.
- Forced Transformation: The wizards' nephew, Quentin, who they lured into coming to their new castle before turning him into a walking, talking mushroom.
- Friend-or-Idol Decision: In one path Jaimie finds a magic book, and can choose to be powerful or to be wise, or to save Pentegarn. Needless to say, the ones that aren't about saving family backfire horribly.
- Imprinting: One way of getting the Rainbow Dragons' aid is their prince imprinting on Jaimie.
- Mushroom Man: One possible ally Jaimie can find.
- Rail Roading: The first two sets of choices in the book are completely meaningless. No matter what you choose, you have to accept the wizards' challenge.
- Ride the Rainbow: The Rainbow Dragons can create a magic rainbow bridge to get Jaimie back from Limbo.
- Schmuck Banquet: There's one in the castle Jamie can visit in limbo.
- Trapped on the Astral Plane: One of the things the trio of wizards suggest Jaimie might do while the grown ups are talking is visit Limbo. Not surprisingly, Jaimie has the opportunity to find some powerful help while he's there.
