Not really too much but I got a little handful for you anon:
- He's the type to sit on the couch and say he's gonna watch TV but as soon as he sits down a few minutes later he's out like a light, head leaned back in that open mouthed snore, but soon as someone touches the remote he's like "IM WATCHING THAT" and then nah he's asleep again
- sprinkling in a little fluffyvenom because I have to, I personally headcanon Snakey as a demiromantic gay man, so while Wolf had already realized his feelings for the reptile well into their friendship, it did take Snake a bit longer and getting to know him to realize those feelings as well, part of that being he'd never felt as close with someone as he did with Wolf
- I feel like he would enjoy golden oreo cookies for some reason
- his collection of hawaiin shirts is insane, half the time he'll notice a new shirt in his closet that he doesn't even remember buying, but he just goes with it cause hey the more the better right
- hates anything thats sour or bitter, Wolf convinced him to try black coffee and it was the worst experience his life
- If anyone touches his family or hurts them he will kill everyone in this room and then himself (pretty much true)
