The seed is -5080311877282610129
A pretty awesome seed with high mountains and some insane caves, with a lush cave being around 120 000 blocks in area and a scattered savanna at 207 blocks in height. It also has a semi buried jungle temple close to spawn that leads you into a massive crater with a trial chamber, ancient city and a pretty big mineshaft at the bottom. The coral reef ravine and the floating islands is just the cherry on top.
