Penguin mod

This is just a mod that adds penguins in cold biomes. For now the penguin it is just an ambient mob but i plan to add more penguin related content .This is my first mod i am planning to make more complex ones in the future

penguins drop feathers witch can be used to craft eye of the sea. When you have an eye of the sea in inventory gives you water breathing and dolphin's grace 

*if you have any problems let me know
