Pair of Kings

During their coronation as kings of the mystical island of Kinkow, twins Boomer and Brady accidentally destroy a sacred ruby, causing Mount Spew to erupt.

Brady and Boomer are banned from the beach by top surfer The Big Kahula. They challenge him to a surfing competition, but if they lose they can't ever use the beach again.

Mason's daughter Mikayla is head of castle security while her dads away, and must cope with Brady and Boomer bringing mermaids to the castle. She ends up getting turned into one.

The twins find a cute animal named Pupaley and keep him as a pet, but having a pet is hard work and when they neglect Pupaley he grows huge and makes them his pet.

Brady and Boomer discover they must go to school even though they are kings. At school, Brady finds Tristan is a rival for Mikayla's affection and must fight for her.

The boys meet a creature called Ogie, but Brady is jealous of him and is mean to Ogie. Brady gets friendly with Lanny, not realising he wants to be King, and Boomer almost becomes dinner.
