Flying Fox: A new mob for the jungle

The Flying Fox is the largest bat in the world living in the rainforests of Asia, Africa and the West, it would appear in the jungles (as mentioned in the title) at night they would be neutral and agitated mobs that can be found in groups of 3-6 they would eat a new jungle fruit I had ideas like Mango, during the day they would rarely be found but when we did find them we would have a new achievement. They would sleep in the treetops during the day, when killed they would release their wings which when combined with the phantom's membrane would make a wing that would fit on the chest (It would be like the elytra but weaker so as not to make combat unbalanced).
