pink river dolphin mob

i think minecraft should have a pink river dolphin mob! its unique, cool, and not many people know it even exists so this will maybe help spread awareness of the amazon being cut down. the mob can spawn in river biomes if they cut through a jungle (not sparse jungle or bamboo jungle) OR if there is water at least 3 blocks deep and in an area of 10 by 10 blocks with has sky above it in a jungle biome. these dolphins spawn alone, spawning at least 30 blocks from eachother, or spawn in pods up to 4. every 30 blocks there is a 10% chance for the dolphin to spawn, 8% chance for 2 to spawn, 5% chance for 3 to spawn, and 3.5% for 4 to spawn. the model could basically be the normal dolphin, but with a longer nose and smaller fins, and a blush pink color with small teeth. they can be bred with raw salmon/cod, or if fed a bucket of cod/salmon they will go to the bottom of the water they are in and dig in clay/gravel/dirt/mud and pull out a random junk piece. it can be something like a bowl, old fishing rod, fish, basically the loot from fishing. they are not aggressive unless attacked, doing 1 heart of damage in easy mode, 1.5 in normal mode, and 2 in hard mode. they will however be aggressive towards guardians and drowned. this mob can have 15 hearts. for their ai, please make it better than the actual dolphins ai, so they basically still go up to the surface for air even when the player is far away.
