Pickle the Pixolotl has spent his whole life wondering one thing: what's out there beyond Wublin Island? When the werdos allow the Tribal Island school to open up to more than just natural monsters, he gets his chance to find answers. But when a certain celestial visits him in his dreams to warn him of a great danger coming to destroy the monster world, Pickle realizes that he has to save it. Join Pickle and his friends as they travel across the islands, meet friends and foes, and wake up Galvana.

Ever since Zyphur's death and her awakening, Galvana has been living on Wublin Island with her dads. But just like Pickle, she doesn't want to stay on the island forever. Although her father worries about sending her to school, Thrum manages to convince him that she'll be fine. However, at school, things are a bit... less than fine. Students and teachers getting sick and coughing up blood, memories of her past life coming back, and a crush on a new (old?) friend. It's time for Galvana to follow in Pickle's footsteps, because there's a new rare wubbox that needs destroying.

After the Continent split, monsters are still trying to get used to life on Plant Island. At least the Wubbox Council is there to "guide" them, although their laws are a bit... much. When Jolthead the Wubbox is banished for their experiments, Basilio must go on a journey to wake up the first Wublin and overthrow the Council.

After the fall of the Wubbox Council, things seem to be getting back to normal. Yet Basilio is worried that many monsters don't trust him, and he sends Ailura on a journey to find new monsters to lead the islands. When danger strikes, she must adapt and keep the leaders safe, but can she protect them from a potential second Wubbox Council?

Laskell is a Xyster who's spent her entire life on Magical Sanctum reading about ancient heroes and the deeds they did. She dreams of someday leaving her island like the great Pickle once did, but it's probably never going to happen, right? After all, the Tribal Island School shut down long ago. There's no reason she'd have to leave. Well, until a strange Glowl crash landed onto her island. Now, Laskell and her new friend Split must face against a danger neither of them expected. It's time to save the monster world... again.
