[TOMT][Kids tv show][2010s] about monsters maybe...?

So.... my memory of this is very vague but I'll try describing anyways

Basically, I remember 2 characters living together (possibly monsters) and they did weird things together. I also remember like a princess or queen character....? I'm pretty sure there was an episode about a love potion but that could be completely wrong too. I know the show started off with a theme song but that won't help.... I feel like the word ugly was linked to it but that could be wrong. I also think a character was called Ed but that could be wrong too. Sorry if this is too vague to figure out-

Edit!!! I feel like I've remembered something else!! I think one of the main characters was green with blue hair or maybe a skeleton or zombie with blue hair??
