I know that ever since the Mink Tribe got introduced, many people have said that Chopper was (somehow) gonna end-up learning how to use Electro, even though managing to produce/utilize Electro is what distinguishes a Mink from an animal and that he’s never displayed an interest in knowing it.
Some have even claimed that Chopper would use his medical expertise to create his own Sulong form after seeing it action. However, once again, that transformation can only be utilized by the Minks after seeing the full moon.
So instead of theorizing what Chopper can learn from the Minks just because they’re both anthropomorphic animals with presumably different physiology, let’s at least look at what we do know about Chopper. He’s a genius medical doctor that’s been able to directly amplify the use of his Devil Fruit through the Rumble Balls as it distorts the nature of his Devil Fruit through years of research. He’s knowledgeable on not only diagnosing diseases but biology and how a specimen’s system can function.
Which is why when I re-read this moment, it could have been a topic of interest to Chopper and something he would look into during the timeskip considering he had a vague understanding of it. He may have done his research over this topic and its’ many applications:
Chopper could potentially find his own way of recreating Seimei Kikan on his body which would greatly amplify his current forms and be able to manipulate/control his body and bodily functions in interesting ways. This is probably why he got rid of Arm Point and Jumping Point, those forms would feel redundant.
Don’t be surprised in the future if Chopper ends up slimming down his Heavy Point, increases the mass in his muscles, or manages to manipulate strands of his fur in some ambiguous form.
