The Red Bluster

, also known as Red, is a red sea monster on The Sea Beast.

Biography
Sea monster hunter Captain Crow had a 30-year vendetta to capture the Red Bluster. He assumed her to be a raging monster driven by nothing but violence. However, Maisie saw signs that Red was a more nuanced and thoughtful creature than she first appeared. Even though Red didn't think twice about fighting or even killing if needed, she was also a loyal and brave friend who only wanted to be left alone to live in peace.

Throughout The Sea Beast
During The Inevitable's attack on the Red Bluster, Maisie cut the ropes attached to the Red Bluster to save both the crew on the ship and the Red Bluster. When Captain Crow was angry at Maisie for disobeying him and ordered Jacob Holland to bring Maisie to him. When Jacob refused, Captain Crow held them at gun point. Seeing this, the Red Bluster swallowed them whole and brought them to an island.

When Maisie and Jacob were attacked by the Purple Crustacean, the Red Bluster came to their defense and attacked the Purple Crustacean. It ended up leaving them alone.

The attack left a hole in their boat. Jacob was adamant that they would use the boat anyway, but Maisie asked the Red Bluster to transport them. She carried the boat on her back. Later, Maisie helped pull out all the spears that were stuck on the Red Bluster's back.

Trivia

 * According to director Chris Williams, the Red Bluster needed to be both appealing and ferocious. She was the most powerful creature in the world, but the producers didn't want her to look scary. They wanted her to be appealing in a very divine way.
 * The team hired a sculptor to craft a clay model that would define even the beast's internal musculature. There were also a few story-based requirements that helped set guardrails for Red’s design process.
 * Unlike other monsters in the movie, Red had no one-to-one real-world analogue. The creature in the film is a pure fantasy, with a few qualities borrowed from real ocean creatures.
 * For inspiration, the team looked into walruses and how they navigate in the water. They also looked at whales, turtles and sharks.
 * The Red Bluster originally had front and hind legs, the producers felt that paddling in the water like a cat was not elegant.
 * The Red Bluster's eyes were inspired by cat eyes.
