Summary
Peppermint Cookie and Sorbet Shark Cookie are using Wave Drop to dive deep to look for Sea Fairy Cookie. They go down deeper than Sorbet Shark Cookie has ever been and meet Lobster Cookie, the guardian of the city of Sugarteara. After they tell Lobster Cookie of their mission, Lobster Cookie agrees to help find her, as it is part of the duty as told to Lobster Cookie by Celestials. Notably, Lobster Cookie does not properly explain who or what Celestials are. Peppermint Cookie informs Lobster Cookie of all they learned during their adventure at the Tower, and Lobster Cookie says Sea Fairy Cookie is likely to have been captured by Mocha Ray Cookie, the temple's caretaker, who Lobster Cookie says wishes to covet the city's sacred treasure.

Lobster Cookie leads them to the gates of the city, and shows off the sugar crystals the city is made of, created by the Sacred Pearl, which also created a replacement claw for Lobster Cookie after the original claw was shattered. Lobster Cookie explains that as the pearl's power waned, the city froze and was abandoned. When Sorbet Shark Cookie attempts to steal some sugar crystals, the group is attacked by two Sea Golems, large rock monsters somewhat similar in appearance to Emerald Golem. As they are slower than the Cookies, Peppermint Cookie and Sorbet Shark Cookie lure them to a position where Lobster Cookie breaks them apart.

The group nears the temple, but blue electric barriers created by Mocha Ray Cookie prevent them from getting closer. Lobster Cookie suggests using Wave Drop to break the barriers, and as soon as Peppermint asks the Pet, the barriers disappear. Mocha Ray Cookie discovers the group after noticing the missing barriers, and welcomes them, but asks them to leave if they have come for the pearl.

Peppermint Cookie says none of them are interested in the treasure, only for Sea Fairy to be free. Sorbet Shark Cookie sees that Lobster Cookie has disappeared, and reasoning that the two of them cannot face Mocha Ray Cookie without protection, the two of them must run into the temple.

Further inside, Peppermint Cookie tires of holding Wave Drop, and Sorbet Shark Cookie offers to hold hands as Peppermint Cookie did up on the Tower. They hear footsteps and find Lobster Cookie along with Sea Fairy Cookie. She is curled around the Sacred Pearl, which is partially covered in shadow. Mocha Ray Cookie catches up, and all eyes are on Sea Fairy Cookie and the pearl.

Peppermint Cookie unsuccessfully tries to use Wave Drop to awaken Sea Fairy Cookie, and Lobster Cookie pushes Peppermint Cookie and Sorbet Shark Cookie aside, harming both of them. Lobster Cookie says a voice said that the city will be saved when the pearl is as dark as night, and Peppermint Cookie realizes that Lobster Cookie was never trying to help and was only using the pair as a means to reach an end more easily. Mocha Ray Cookie is still present, and declares that even if it results in death, she will stop Lobster Cookie. After a rumble, Sea Fairy Cookie wakes, and asks what is going on.

Sea Fairy Cookie notices the darkened pearl, and is worried she will never see the moon again if she uses her power now. She sees Mocha Ray Cookie and Lobster Cookie fighting, and asks who they and Sorbet Shark Cookie are. Peppermint Cookie tells her to run away with the pearl, but she refuses after watching the fight. Sea Fairy Cookie absorbs the Sacred Pearl, and Peppermint Cookie worries she will turn to sea foam, but her Pet starts to glow, opens its wings, and goes to her. She is warmed by Wave Drop, but the sugar crystals all over the city start to break and are attracted towards Sea Fairy Cookie, including Lobster Cookie's claw and Mocha Ray Cookie's head gem.

The city has completely fallen apart, dismaying Mocha Ray Cookie. Lobster Cookie has escaped, and Mocha Ray Cookie explains to Sorbet Shark Cookie that the guardian was not evil, just misled. Sea Fairy Cookie apologizes, saying she hid her feelings in the depths and darkness would've enveloped the entire ocean if not for Mocha Ray Cookie's barriers. Mocha Ray Cookie says the city only ever existed because of her, and that making a city using the pearl was a mistake to begin with. Mocha Ray Cookie stays in the deep to look for Lobster Cookie, still considering the other a friend even after their fight. Mocha Ray Cookie even mentions her desire to possibly build a new city together with Lobster Cookie. The others bid her farewell, and head to the surface. Sorbet Shark Cookie still has one sugar crystal, and is pleased to not have to return to Pirate Cookie empty-handed.

Back on the surface, Captain Ice Cookie, Pirate Cookie, and their crews are hauling ice to keep the Tower of Frozen Waves standing. Captain Ice Cookie is happy to see Peppermint Cookie with Sea Fairy Cookie, but Pirate Cookie does not consider the single sugar crystal to be treasure. With Sea Fairy Cookie safe, the pirates and the navy return to their own ships, and everyone waves goodbye to each other.

At the bottom of the ocean, Lobster Cookie is laying down and is approached by Eerie Anglerfish. In contrast with all others in the story, it has deep red text. It is revealed to be the one who had been giving orders to Lobster Cookie, and was not expecting Sea Fairy Cookie to recover. Lobster Cookie thinks all is lost with the destruction of the city, but the Pet says it has a new offer Lobster Cookie cannot refuse, as its eyes and lure glow red.
