The Nether Landers

The Nether landers are large bat like creatures (a little bigger then the player, wing span including body 5 blocks each wing is 2 blocks) that spawn in the Nether. They are neutral mobs but if they are attacked they will try to knock the player into lava with their wings. They drop magma cream and leather when defeated. They are not hurt by lava or fire and if they fly through fire or lava their wings will start on fire and they can  do more damage the player with them.
