Silly Syringeon au headcanon:
He LOVES to be pet. He also purrs, letting out tiny chittering sounds as well!
The only people he lets pet him are Dadadoo and Bouncelia. This is because they’re the only people who can do it properly. Plus, it’s a lot of trust for a man who is so distrustful of everyone.
Bouncelia opts for his facial area (sensitive because of ampullae of lorenzini). Dadadoo goes for his cheeks or his back, or the sides of his head.
I can imagine a scenario during the rebellion where he refuses to let himself rest while the others plan things out, and bouncedoo have to jump his ass and love bomb him.
Meanwhile, he’s letting out the loudest rumbles, his tail thudding loudly against any surface around him, and likely kicking his leg in rare happiness 💔
Syringeon is secretly touch starved and I love him!!
