R-8 "Living Bricks" are ROBLOX part instances that move on their own, regardless of being anchored or not, and open up to show what seems to be flesh. R-8 can appear when a new part instance is put into the workspace, these instances seem like they are alive. The affected part seems to be able to support all of the features you can add to a normal part. However, attempting to duplicate the anomaly will result in the copy to not have these anomalous characteristics. When putting your camera to look inside of the part will show that there is flesh and you can hear raspy breathing; although in the worspace, the part shows as a normal part without any sounds or scripts. Although the outer layer of the anomaly is unaffected by damage, the inside can be affected by scripts that will damage humanoids; dealing damage to the part will cause it to scream loudly and crash the client. Looking at the output, R-8 printed the phrase "PAIN" over and over until studio crashed. Overall, it is best to ignore R-8 if in game, or delete and readd the instance if found in studio.
