i think it could be really fun to write a crowmonster!philza and warrior!etoiles au for the soul purpose of writing their little "sparring" matches where instead of beating each other with sticks it's just etoiles wrestling his big ol dragon-esque monster friend. etoiles clinging onto phil's back/tail feathers as phil tries to buck him off. phil holding etoiles in his beak and shaking him around like a chew toy. etoiles hooking an arm/rope around phil's throat and phil doing this great big dramatic roaring cry as he stumbles and flops onto his back and "dies", talons in the air, twitching, also crushing etoiles in the process. everyone else looking on with bewildered concern as phil seems to be gnawing etoiles' arm off and etoiles is just lying there declaring deadpan, "ohhh no he is too strong, the monster has defeated me, he is killing me, it is so slow and painful, i am dying, ggs bro, ggs." (<-he is perfectly fine, phil is only play-mauling)

other fun points:

phil tossing etoiles around in the air like he weighs literally nothing

etoiles pinning one of phil's wing-arms behind his back like its no big deal

etoiles ripping out some of phil's feathers during one of their play fights and phil freezing mid-thrash just to shoot him the flattest, most offended look to ever come from a non-human creature

phil accidentally going too far and ripping up etoiles' shoulder and phil just becoming the biggest, most whimpery apologetic mass of feathers and spikes as etoiles pats his beak and tells him it's no problem, it doesn't even hurt that bad (and phil just wails louder)

both of them nudging/bugging/poking each other when they're bored to goad the other into a play fight, with varying degrees of success
