“Jumanji: Welcome to the Sea (2026)” is a title that looks very real at first glance, especially with convincing trailers and posters online. However, the truth is that this is NOT an official film title. It is a fan-made concept idea, not an actual confirmed movie by Sony or the creators of the franchise.

This means “Welcome to the Sea” is simply one of many imagined directions fans have created for the next chapter.

Despite being unofficial, the concept itself is interesting enough to analyze like a real movie.

The idea behind “Welcome to the Sea” reimagines the Jumanji world by replacing the jungle with a vast ocean environment. Instead of surviving wild animals and temples, the characters would face storms, pirates, sea creatures, and constantly shifting islands. This change fits well with how the franchise has evolved—from a board game in 1995 to a video game world in 2017—so expanding into a new “biome” like the ocean feels like a natural next step.

From a storytelling perspective, this setting could bring a stronger sense of unpredictability. The jungle in previous films had clear terrain and goals, but an ocean-based world would remove stability entirely. There would be no fixed map, no safe zones, and danger could come from any direction at any time. That kind of environment could raise tension and make survival feel more intense.

In terms of characters, most fan versions keep the familiar cast—Dwayne Johnson, Kevin Hart, Jack Black, and Karen Gillan—returning as their in-game avatars. This aligns with what is expected from the real upcoming film, where the main cast is also likely to return.
The dynamic between these characters has always been one of the franchise’s biggest strengths, blending comedy with action in a way that appeals to a wide audience.

However, the ocean concept also introduces potential weaknesses. One of the reasons the jungle setting worked so well is its visual variety—dense forests, temples, cliffs, and wildlife. An ocean environment risks becoming visually repetitive unless it includes diverse elements like underwater ruins, floating cities, or mythical locations. Without that variety, the film could lose the sense of adventure that defines Jumanji.

Another challenge is tone. The recent Jumanji films are known for balancing humor and danger. A darker, more survival-focused ocean story might clash with the lighthearted style that audiences expect. Maintaining that balance would be crucial.
