What is Christmas present Tohru gives Miss Kobayashi in episode 10? At time mark 20:11 of ep.10 in Miss Kobayashi's Dragon Maid, Tohru gives to her a Christmas present to help with back pain. She opens the present, which is apparently some sort of living creature from Tohru's world which must be ground up before use.  However, the anime on both Crunchyroll and Funimation censor it with a heavily pixelated effect.



What is it? My research shows this is an anime original episode, so I guess the manga would be no help. I've checked other forums where this question has been asked, but I did not find an answer.
This is just how anime shows "a very disgusting thing vaguely shaped and colored like this".  It's not a new thing, off the top of my head I can remember one other instance for which we have a question here: Why are there censored/retracted art when there is no problem and here's the video of that fragment. Also see this question and its answer: Why do they censor vomiting in anime?
