Giant bugs

This is a few ideas that i think could work with the caves and cliff or any updates, I got this idea from a video with a old picture of the lava walker, it looked like a beetle, and when i thought about it more, the new plant filled cave would be great for a few bug mobs. so ill toss my hat into the pile, and give my idea to the community.
