They like to roost on the ceilings of deep-ish crimson caves, and then drop down, spinning like a drill bit, on their prey. They cause severe harm. About... 40 damage? They're an early enemy so... good if you ask me. Once they're on your head, spinning and spraying blood particles about, your HP drops by 5 DPS. Use a broadsword or something else that can aim up to dispatch them and GERROF! Sprite 1: Damn, small... but it'll be the right size in Terraria, according to my possibly rusty calculations! I will do the rest of the spinning animations later, or maybe I'll get a friend to. Anyway. While they are falling towards you, they spin faster. While they are on (in) your head, they spin REALLY fast. The longer they stay there for, the faster they go and the more blood comes out... gross... BLECK! Spoiler http://www.metroid-database.com/manga/shounen_oh_en/ch_0001/scaled/sc_HGCSM_011e.png Read the one on the left mainly, although the right one is pretty damn funny too! I used the word 'BLECK!' which reminded me of the 'BLECK!' in that comic strip. When they hit the ground, which is if you manage to outrun them as they SPIN TOWARDS YOU! Then... they just sink into the ground. Drops: 50% Vertebrae 0.1% - suspicious looking eye 0.4% - Blood-clot drill bit Craft the blood-clot drill bit with a pickaxe and a few wires to make... the crimson skroth drill! use it to drill reasonably fast, through the last tier before hardmode of blocks. Eh... room for improvement.
