Cadence and her grandchildren Marella, Vox, Sid, and Evil Susan return from a holiday vacation to a tropical island. Marella recounts their adventures, which included exploring a pirate ship, soaking in hot springs, and an unfortunate incident where lava shot out of the ground. They also met a mysterious local Twikki man and learned traditional dances. Though the trip was fun, Marella was disappointed she didn't get a suntan like Sid did. Back home, Ivan continues to bully his cousin Callisto by refusing to share toys and threatening to bite her.
