Sulphur Sniffer Variant

Hello, I've noticed the update feels a bit incomplete! So I have an idea to add something that will add more life to the Sulphur Cave biome!

Meet the Sulphur Sniffer variant! Sulphur sniffer is a new variant of the sniffer. It can be obtained by feeding a sniffer a bucket with sulphur cube.

Sulphur sniffer has Sulphur biome colours and is passive towards player. Sulphur sniffer can follow player around, unless leashed to fence, and will attack aggressive mobs near player, by spitting sulphur cube goo at them. Such attack deals 2 hearts of damage and nausea effect to enemy. 

Sulphur sniffer, while being inside sulphur caves biome, OR in radius of 6 blocks from sulphur spring can dig up sulphur spikes, glowing lichen and potent sulphur.
