My personal favourite is a parental relationship with c!Puffy, c!Eret, and the rest of the server. They're like the cool platonic lesbian mums that give awesome hugs, delicious cookies, and genuine life advice. c!Puffy is just a wholesome presence, especially when Dream was following her around like a duckling, and c!Eret seems like a good parental figure. I know she didn't turn up for c!Fundy's adoption, but that was a communication error on everyone's part. You can't adopt someone if you're not told when/where you need to be for adoption.
Dw, Dadza is still there and as awesome before, but lets be honest, the server is a bunch of emotionally immature/stunted kids in adults bodies and the server needs more levelheaded parental figures around.
Most of my personal favourite ship dynamics aren't romantic. DNF is another example of a platonic situationship; they are both aware they're not in a relationship, but they're both comfortable enough with their respective sexualities/identities that they don't have a problem with making it everyone else's problem. (aka publicly flirting and making it very awkward) I headcanon that only a select few people know that they aren't actually sleeping together.
