I stumbled into Snorpy and Chandlo fanfic totally by accident, honestly. I was just browsing for more 'Bugsnax' stuff after finishing the game, and some writer had them in a modern coffee shop AU. That seemed random, but it worked? The core thing I see writers doing is using Chandlo's straightforward 'let's go, bro!' energy to gently pull Snorpy out of his paranoid, overthinking spirals. It's never about 'fixing' Snorpy, which would feel cheap. Instead, the stories show Chandlo patiently waiting outside the lab door or dragging him on a simple walk, forcing Snorpy to engage with the world beyond his theories.
Where the emotional growth really clicks for me is in the quiet moments after a crisis. Snorpy has this whole breakdown about a flawed snax trap or a perceived conspiracy, and Chandlo just... sits with him. He doesn't dismiss the fear, but he grounds it. The growth is in Snorpy learning to trust that one person won't judge him for his anxieties. I read one where Snorpy finally admitted he was scared of being left behind, not of grumpuses plotting against him. Chandlo's response was just to flex and say 'Nobody's leaving my best bro behind.' It was so simple and perfectly in character that it actually choked me up a little. That's the dynamic that makes it work.
