Two official movement examples
New Tales describes One crashing down as a water bomb and ascending in a vapor burst. These terms establish that water transformation supports vertical movement as well as traversal through cracks and tubes.
Keep the claim narrow
The official description does not provide a complete move list or timing data. Treat these as movement concepts and learn their exact controls and limits in-game.
