Take the Nothosaurus to the shallow waters near the beginning of the game. Note: A challenge portals is at this location. Notice the island with a tree. Use Nothosaurus' land walking ability to get on the island, then try to climb up the tree. If done correctly, Nothosaurus will appear in the air while swimming. You can now swim through the air. Note: If Nothosaurus touches water or land, movement will return to normal.
