New Lake Biomes & Freshwater Ecosystems

Minecraft should have actual lake biomes, rather than lakes simply being random bodies of water.

Possible lake types:

* Huge freshwater lakes

* Forest lakes

* Mountain lakes

* Tropical lakes

* Rocky lakes

* Volcanic crater lakes

* Alpine lakes

* Lakes with small islands

* Lakes surrounded by cliffs

Lake environments could contain:

* Reeds

* Cattails

* Water lilies

* Willow trees

* Wildflowers

* Rocky shorelines

* Small islands

* Waterfalls

* Fishing areas

* Docks

* Piers

* Cabins

* Boathouses

Some lake regions could be inspired by real-world lake environments, such as a Lake of the Ozarks-inspired region with rolling forested hills, coves, islands, docks, cabins, and wildlife.

Otters

Freshwater lakes and rivers could have otters. Otters could:

* Swim

* Dive

* Play in the water

* Live in family groups

* Have babies

* Collect small objects

* Live in small dens

Players could befriend/tame otters using fish. Once befriended, they could swim alongside the player, play around their base, and interact with the water. Sea otters could live around ocean coastlines and kelp forests. They could have small dens under rocks, along coastlines, or inside little caves.
