Ik that title is odd but it makes sense if you keep reading-

Ranboo: has a purple tongue that also is pointed at the end so its not rounded at the end but its kinda pointed. The tongue is only purple when he is full enderman/ mostly enderman tho.

bbh: has a long tongue. like a l o n g one. Its either red or black. I get this because he is part demon and I see some types of demons to have long, pointed, or oddly colored tongues. 

...thats it- thats the chapter. Might update it some day if I get more ideas for this topic but I just had to post this cause its been in my head for a few weeks.
