If you have the time, could you make a spider eye (Raw, Unfermented!) texture that looks/peeks around, and squirms and wriggles occasionally? (This may be a challenge, but is possible with animated textures!)
Thanks in advance if you give it a shot, and if you don't, I understand and thank you for your time reading this.
Just please remember that I'm only doing single blocks. Not mobs, whole texture packs, etc. Only blocks. Maybe a tool from time to time if you're special enough, but yeah.
Oh, didn't see that at first. Sorry! I'd imagine a spider eye would be simpler than a tool, but am not an expert, and don't know if I count as "special" enough for that big of a rule-bending. If you can, thank you, and that helps a lot.
