New Pale Garden and Creaking are interesting but lack purpose

Mojang just revealed the Pale Garden biome and Creaking mob, and to be honest, it's really underwhelming. There's no reason to visit the Pale Garden besides the woodset, and even then, you don't ever have to encounter the Creaking. The Creaking doesn't drop anything of use, so it's just another useless mob. I like the idea, but its just pointless.

what are your thoughts?
