Splash and Bubbles follows the adventures of Splash, a yellow fusilier fish who has migrated all over the oceans before settling down with his family in Reeftown, where he befriends three inquisitive fellow sea creatures. Until Splash came along, Bubbles, Dunk, Ripple and most of the other Reeftown residents had no idea what lay beyond the cozy confines of their coral walls. Together, Splash and his friends explore the world’s oceans, where they meet wildly diverse marine animals and discover otherworldly undersea habitats, bringing back what they’ve learned to share with their neighbors.
Dunk meets Puffy, a female pufferfish who admires his sand patterns and becomes friends with her! Then, Splash experiences his first earthquake on the reef! Bubbles and Dunk attempt to find out what caused "the big shake.”
