No Whamon

Summary
Escaping from Seraphimon's castle, Kettle the Trailmon brings the children to an underground cavern and Bokomon takes Seraphimon's egg from Zoe to properly hatch it. Unsure of where they are, the children begin to look for a way out, but they only find a large, icy cavern with a pool in the center. The group begins to look for an exit, but suddenly Whamon appears from the pool and is uncharacteristically out of control. Koji and Takuya both spirit evolve to calm down Whamon. Zoe asks him what's wrong and Whamon tells them about how he was trapped in the cavern after Grumblemon stole some Fractal Code that resulted in part of the ocean being sucked into the cavern. Grumblemon, having seen Kettle head back toward Seraphimon's castle and backtrack the way he came, appears and uses more magic to create a small army of Golemon. Arbormon, who was hidden, grapples Lobomon and Agunimon, taking them out of the fight and beating them. No longer able to stand on the sidelines, Tommy and J.P. spirit evolve. J.P., however, was accidentally injured by Whamon when he was thrashing around and is quickly defeated. When Grumblemon moves in for a finishing blow, Whamon attacks with Blasting Spout, also releasing the Beast Spirit of Thunder that he had accidentally swallowed. J.P. beast spirit evolves and easily defeats Grumblemon. He scans Grumblemon and returns Zoe's spirit to her. However, the cave begins to collapse due to damage it took and water rushes in. Whamon takes the group into his mouth and returns to the ocean, ferrying them to an island as thanks.
