[1.12.2] Suggestion - Foxes and/or dolphins

[ElLiox]

first of all, sorry for my bad english, it's not my native language I really like this mod, it helps a lot to feel the game fresh and new playing old versions however I miss seeing the cute foxes and dolphins I think these two would be a great addition considering that they are two mobs that dont drop loot It would also be nice to have the turtle back, but it also includes 2 items and a new potion, so adding it I think would be more difficult to add to the mod
