(Nether) Nekos

Basically they would be a new mob that spawns in the Nether. They would be like Geckos in appearence but are blue and have the ability to climb walls, and are quadrupedal with the ability to go bipedal. They will be neutral unless attacked or the player goes near their alpha (distinguished by a red mane). They attack by biting (if quadrupedal) or scratching you with their claws (if bipedal) and can also shoot lava out of their mouth like a flamethrower (for only a second and they shouldn't be able spam it either). They could drop some Neko claws (which would basically bones) and slime.
