rainforest idea

This is the idea I had that I described in the "ideas" post.

As they enter different worlds, an underwater seaworld infested with dangerous sharks and a world that was hidden behind the curtain of the rainfall, but they both reunited through the random mirror the person swam through to escape the sharks, which brings in the impossible world. They then walk to the end, where they end up in a safe part of the rainforest, free of sharks and rainfalls, as they exit their nightmare rafting.
