Shores are a type of Biome in all current Creativerse gameworlds.
Pretty much every type of Biome connecting to Oceans is usually wrapped in Shorelines, except for Swamplands. Even lakes or rivers can sometimes be seamed with Shorelines, however not always adorned with Shorewood trees.
Occasionally palmlike Shorewood trees can be found on Shores, consisting of Shorewood, a frew blocks of Shorewood Husk near the top and Shorewood Leaves. Shorewood currently cannot be grown from Saplings, and no Flowers nor Fruit will grow on them, not even Beeswax.
When hunting Rocksters for their Rockster Rocks, remember that 3 Pebble's Pebbles each can also be melted/merged into 1 Rockster Rock in the Forge. However, even though Pebbles seem to be easy prey, they are able to call other Creatures to their aid when they are attacked.
Caves with entrances on Shores often feature some Stalactites closer to the surface than common Caves do. Shore-based Caves are also quite likely to have pools of Tar inside. Sometimes their entrances are not easy to spot as Water might flow inside and rarely can even cover all of the entrance.
