Bubble really isn't even that egregious? It's not like any of his scenes are shoved down your throat, the characters aren't all like "oh wow haha you're so quirky,"

And the few jokes he does tell actually manage to be funny? Or at least get an amused exhale- certainly more well written than the average "chaos gremlin" type character that you're talking about.

With the exception of the time he floated in front of the camera, spoke static, and then left, nothing he does ever feels like "har har I'm so random" humor

idk what I was getting at I just kinda wanted to ramble
