Kanoa found the ship he was looking for but he also saw that this Dhelmise was guarding it. Team Rocket decided to approach the ship but they were stopped by Dhelmise, who would attack them if they do something to its ship. After shaking the submarine, Team Rocket's Meowth pointed upwards to the boat the heroes were on and said that they were the ones he should attack. Dhelmise then attacked the boat and bound the boat with its anchor, preventing it to escape. Ash's Pikachu used Thunderbolt but Dhelmise was unaffected by it. Ida's Brionne used Aqua Jet which hit Dhelmise but Dhelmise hit Brionne back with its anchor. Dhelmise continued to pull the boat into its whirlpool but when Lana's Popplio used Hydro Vortex, it became overwhelmed and was blasted away further into the sea. At the end of the episode, Dhelmise is seen with Team Rocket's abandoned submarine.
