I got frost walker boots from an end city and walked over to my sugar cane to check on them (for context it's on the shoreline of a large lake) and I forgot I had frost walker. I decided to cover the whole lake for fun but then the ice wouldn't go away and I was like really confused but then I thought about it for a second and thought of a way that I could exploit this so I went to the ocean and made a very long ice path and went around on it with a boat.
