After 3 weaks of scripting, modeling, animating, sound designing etc I have a preview of how first Boss fight will look like. (this boss will be on different arena, but fight will be the same i think)
This worm boss Can shoot acid projectiles, change places, use various attacks and bite player from underground making him bleed for few seconds. Also during the fight he spawns eggs, and if player will not kill those before those eggs explode, he will have to fight little baby worms… and those worms are not so cute as they looks like 
And a gif from a 3D concept of arena, where this boss will be placed
