A new mobs :the snake and the lion

So I feel like a snake would really be cool with more variations like cobras and normal also having some be venomous and some not with them able to be tamed with raw rabbit and that ends my idea for the snake now onto the lion so I think it would be cool for a lion to be a mini boss like the warden and wither but a bit less powerful like 2 hearts of damage and 20 hearts and you could tame the lion with steak and mutton because there is not enough cats or mini bosses and that ends my ideas bye :) MOJANG PLEASE SEE THIS
