A Mermaid's Memories! Reclaim the Ocean Ring! is the 37th episode of Tropical-Rouge! Pretty Cure.
The Cures learn that the Witch of Delays wants immortality. Meanwhile, Laura uncovers a secret about her childhood.
Tropes:
- Amazing Technicolor Wildlife: There's a painting in the Grand Ocean of a blue and yellow seal fairy, who looks quite similar to Kururun.
- Forgotten First Meeting: Laura actually first met Manatsu when she were small children, and played together on the beach, with Laura staying in the water to prevent Manatsu from seeing her mermaid tail. However, Laura had her memories of that day erased.
- Jaw Drop: When Manatsu learns of the Witch of Delays' desire for immortality, her jaw drops so far, she could fit a football in her mouth.
- Shout-Out: One of child Laura's drawings on a rock is of a cruder version of the Octonauts' logo.
