The Dolphins World is a Collection of 5,000 Unique Dolphins living in the Polygon Blockchain. The NFT metadata is hosted on the IPFS with Pinata. In the year 2033 dolphins have conquered the world. They were smarter than humans and were planning the invasion for years. Humans lost the war and the survivors had no choice but to go on spaceships to Mars. Now, there are four tribes in the world. These are: Tursiops, Snubfin, Stenella & Inia. Each of these tribes believes they are the best and they wont stop until they prove it.
