A new possible mob

a new passive mob that spawns in snowy spruce forest and spruce forest, very similar to a strider but for powder snow, I personally think it should be a duck with big feet to traverse snow but you guys can change that if you want, I just want the mechanic of a rideable mob that lets you traverse powder snow, and if not this at least ad boots or snowshoes for horses to wear that keep them from falling into powder snow.
