Honestly, this is using a calc making an assumption that bug is that big on the same assumption we assume his nail is how big it is. The fact bug sizes are inconsistent. Tiny bees smaller than The Knight exist. And so do large bees, adding in that their Rain is normal sized. Which even a light s rain would have large drops for something that small. But rain seems to be average sized for them. We shouldn’t debuff it based off this considering we don’t know if that bug is really that big. It’s not the most trustable source. Really, this verses size is extremely hard to land. Many looks can change how big they are.
The nail looks nothing like the nails used to scale from. The Stag Beetle looks normal and is called a Stag Beetle.
Grubs and stuff exist and actual bee size isn't that far off from the knight, and water doesn't have a minimum droplet size. They're also underground except for like 2 areas, and there's no rain there.
