Themed Forests

 is a set of Biomes in Lego Worlds. They encompass a set of 4 biomes; namely Cherry Blossom Forest, Forest, Autumn Forest, and Winter Forest.

These can be considered a set, due to the fact that they share a similar underlying theme (Forests), with slight variations on the central idea. The forests appear to be themed after the four seasons.

Spring
Cherry Blossom Forests are themed after the season of spring, as evidenced by the Cherry Blossoms, which are a common spring theme, especially in Japan. This relation to Japan is also seen in the presence of Pagodas, which has a roof style specifically tied to Japan.

Summer
Forests can be argued to be summer-themed, due to the presence of green leaves on the trees. Additionally, with the others being clearly season-themed, it would make sense for Forests to be season-themed as well.

Fall/Autumn
Autumn Forests are themed after the season of autumn/fall. This is evidenced by the colors of the foliage, and the leaf-covered ground.

Winter
Winter Forests are themed after the season of winter, as evidenced by the snow-cover and occasional Snow People, which are common themes of winter in areas with colder climates.
