Ok so I found this awesome seed that spawns you on a island out in the middle of the sea. Wait on the island with the "Render Distance" on normal or higher and look for any other land. If you did it correctly there should be a flat walled, glitchy looking island thing. Go there and then either travel on to the dessert extreme hill things or dive under you ocean to the awesome underwater cave the leads to a ravine! You choose! The seed is RingRingRing!
