The skeleton was frightening, like Sans he wears the usual clothes, changes were that there was cracks in his head and his white eyelights shrinked into a size of a pinprick similar to a dot, there was blood all over him and he was twitching and shaking intensely. He held his Papyrus' jawless head in his right hand, it was bloody hell- it looked like it was still alive with the eyes shaking intensely. Insanity Sans has an unusually large smile, there was also visible wounds in his body.
