Toxic:.Jaw change

I promise, the next drawing will be a commission >:c

(the pink stuff doesn't belong to the design, it only shows where his jaw is)
_{I wanted to make a little Toxic sketch, when I realized that it isn't possible for him, to bite 'cause his jaw wasn't connected with his upper skull :I}
So I changed some things, and fixed the anatomy
WHOOP orange blood ftw

Story of the three threads:

When he was insane, he was able to open it much wider a bit like this:

there're many teethes inside his throat 'cause he just...well if you know how it looks like when a crocodile/_bigsnakes or even birds eat, you know how he does it. swallowing the whole thing, and you see the 2 bigger 'holes' in his neck? they can close and move, so he's able to tear his prey in shreds while swallowing it c: isn't that lovely?
his teethes are tiny, razor-sharp and hard like diamonds

ah and the inside of his throat automatically starts to glow when he opens his mouth to eat _{can be irritating sometimes}
