one of my personal favorite rocket headcanons is that his tail uncontrollably wags when he sees the person he's pining over. even the mere mention of your name has his tail doing these little flicks of interest.
and it goes on for sooo long before anyone even brings it up to him, like he seriously thought he was being super stealth and keeping his feelings under wraps that not even you know. nope, everyone on knowhere knows because he turns into Cosmo when she sees a new treatbag everytime you talk to him.
follow up headcanons: rocket excessively rubs his hand together when talking to you and goes out of his way to touch you to mark you with his scent and has no clue why he's doing it until Cosmo says you reek of him
