A Silkworm-infested tree
Silk worms will infest any tree (even modded ones) and the leaves will lose their color as the infestation takes place.
An Island with everything
Shown here is a cobblestone generator, a netherrack generator using Witch Water, Oak Crucibles melting leaves into water, sieves filtering through gravel, barrels composting apples and carrots into dirt, and porcelain crucibles melting stone into lava.
The six Sieve meshes
There are six types of meshes usable in the Sieve: String, Flint, Iron, Golden, Diamond, and Netherite.
