Add the old OG ravines ,caves and underwater canyon. Also, new animals.

I watched survival series of some old youtubers (started 6 yrs ago) where they got many resources from the ravines which were WAY better than the gigantic caves and spaces beneath the ground in the game today. But the deepslate stones are also so nice. Pls let both be in the game . It felt so nice to find a ravine with lava, water coming out and lots of iron. The underwater canyons looked something unique with the obsidian and magma blocks. If u could add these in the next 'Dappled Forest' update which have such nice Poplar trees . Wouldn't it be nice to have some new animals in the forest like raccoons (a great idea from a youtuber I saw) and deers. This is the best game ,and it would become even better with the OG ravines, underwater canyons and new animals, thnx.
