They make webs in like a plus shape and that catch birds flies bees and fire flies. A spider can freely move through web pixels and will go towards any living thing stuck in its web and eat them.
So bees will go and rest on flowers for a wile. And after that they will go to a bee hive pixel and add a new pixel to it. And bee have pixels will spawn a bee but only one per pixel and if that bee dies it will spawn a new bee
Also seeds should only be able to grow on dirt and mud and permafrost ect pixels. Am tired of having pine trees growing on glass and flowers growing on top of other flowers
