They just want a situation that leads to everyone getting what they deserve, good and bad.
I feel like Lemon, if they got to meet the main Undertale crew, would absolutely love Undyne. Maybe Sans too but only if they witnessed the Undertale Genocide route. They'd want Undyne to lift them like a weight and they'd want Sans to use his telekinesis on them.
I think they may have a thing about being held in the air. Like, just hold them in your arms? Eh, sweet though. Bridal carry them? Yippee! Free ride! But literally hold them up above your head, they are basically a happy puppy. Just absolute joy.
I also feel like they'd love very small things, like snails, ladybugs, little lizards, ect. They just want to either old them or get on their hands and knees to watch them crawl around.
Lemon is just my little sourpatch kid <3
