Well, i did what (from what ive seen) barely anyone did
I represent to you, my "headcanon" on how a Mawiles Headmaw swallows things:
Through the back of the head and into the Main Throat once the Prey reaches its Neck

As Noted in an Edit on the other Pic, his Name is officially changed to Onno, the right Headmaw being Futa and the left one Kuchi (Pronounced like Cookie, but with a soft "k")

And for those who actually read my Descs, let me indulge you into further Mawile Headcanons:
- The Headmaws have a seperate, although very small Brain for themselfes, making them able to be sentient, have own personalities etc. This also allows them to stay Guard while the Mawile is sleeping
- The Mawile itself can still bruteforce its own will into its Headmaw/s, in Situations of disobedience
- If anything happens to the Mawile, they all share the same Pain
- If the/one of the Headmaw/s die, aka their Brain stops working, it can only rely on Mawile bruteforcing it to keep going on, making it hard for it to Multitask
- Although Vocal Communication is preferred, they all can Communicate through thoughts to each other
- If needed, the Mawile can "mindread" its Headmaw/s
- They all can taste everything at once, though the Mawile itself can sort of "shut it off"
- Only in Mega Form, do the Headmaws also become additional Stomachs, meaning they can produce Acids inside themselfes, helping to process immensly large Prey that the Mawile usually could in no way get swallowed down. These Acids however, are only strong enough to get the Prey into small pieces so that they can swallow some of them, and let the Mawile finish it.
- This also means that they can be great Food Storage in case of emergency
- And as a small, last fact: The Headmaw/s only communicate vocally via Groans, Grumbles, Murrs etc. All of which the Mawile of course can understand perfectly
There might be more, but for now, have these. Let me know what you think of those if you wanna o3o
