My idea

Hey minecraft do you think that minecraft needs some more fun stuffs well with the yeti boss now if someone finds shallow ice and break it there is a chance they fall into the ice dungeon and stuff could be frozen into the ice and if they do some ritual the yeti in the ice explodes out and with his ice attacks he drops yeti fur and don't worry there isn't only one there can be multiple of this biome and they can make a yeti coat and if you don't wanna add this you can make this into an addon on the marketplace
