To elaborate, I don't think Aquatic and Dramps mean you literally
make Hisuian Voltorb by crafting, but that they might spawn nearby after you make Poké Balls instead of having a fixed, natural habitat in the wild! It's just like this old entry of Voltorb's:
Voltorb was first sighted at a company that manufactures Poké Balls. The link between that sighting and the fact that this Pokémon looks very similar to a Poké Ball remains a mystery.
Voltorb are known to appear on their own, for reasons no one can explain, when people
make Poké Balls - in Legends, you're the one
making Poké Balls yourself, so they saw the potential to put you in the shoes this entry describes and tie a variant into a brand-new mechanic.
These aren't some kind of "natural descendant" of Voltorb - they are the
kind of Voltorb that spawns unbidden
(who knows why? what a mystery!) when you craft Poké Balls the way people do in the time period of Legends, just like Kantonian Voltorb is the
kind of Voltorb that spawns unbidden when modern factories craft modern Poké Balls the way people do in modern times, and each form is exactly as unnatural and inexplicable as the other.
The Hisuian thing here is not Apricorns, these Voltorb clearly do not grow on trees, and their mechanical role in the game is not to be an item ball mimic - the Hisuian thing is the change in the
development of Poké Balls (from a design perspective, in the kinds of Poké Balls that are made; from a gameplay perspective, in the way you, the player, acquire new Poké Balls), and Hisuian Voltorb's mechanical role in the game is probably being a Pokémon you get by using that new feature, designed to give the full "Poké Ball manufacturer experience (TM)" in what's honestly a really cool and unexpected way!
This is also probably why they have the size difference mechanic, incidentally!
Because crafting Poké Balls is a mechanic you use
all the time and there's exactly one (1) Pokémon that makes any sense to spawn from it, they wanted to give a reason to be excited about catching more than one Voltorb, so they made a cute collectible out of it to spice up each encounter and make sure it wasn't just a one-and-done gimmick that became a nuisance afterwards.
I would in no way be surprised if these turned out to be the only Pokémon in the game with size variations like that (think Pumpkaboo, not a game-wide feature), but even if not, it's clearly deliberate that this is the one that was shown off as the face of it and the first we've seen of it! Either way, these forms play so neatly with the gameplay purpose Voltorb fills here and I think that's really cool of it C:
When it was first leaked that we'd be getting a Hisuian Voltorb, especially when it was increasingly suggested that it would be Grass-type, I honestly had
really low hopes for it, because I
thought it would just be a shallow copycat of Voltorb's mimic idea forced into Apricorns purely because Voltorb was already Poké Ball-shaped - that, and/or a weird, retconned backstory connecting it to Apricorns that didn't mesh with the way it's is presented in the present.
I could not have been less interested in it based on my expectations at the time - if they were making a mimic Pokémon, I would have wanted it to be something more novel and specific to the way you
get Apricorns.
(My personal take was a Hisuian Pineco that uses Apricorns as shells, linking to the fact that we get Apricorns by knocking them out of trees like Headbutt and that they're known for exploding - perhaps evolving into a Forretress that adds wood like Pineco uses tree bark, since Forretress already has about the right shape and palette to be easy to give a Poké Ball-esque appearance and comes with abundant potential for the same sort of "explosives from a hole on the top" we see Hisuian Voltorb playing with. I am still attached to this and I still think it's a great idea)
If
that were the territory Voltorb were setting out to cover, and if the
only reason Voltorb was chosen for the part was because it was already a ball mimic and it was the "obvious" thing to tweak for the part, and if
all of the thought that went into it was "hey it's the Poké Ball Pokémon! Poké Balls have a 'Hisuian form' - so should it!" I would have been incredibly underwhelmed; my friends on Pet Mods and I have been collectively grumbling for ages how little sense the idea of Hisuian Voltorb made and how unnecessary it sounded as an addition.
But!!! as it turns out!!! that's
not what Hisuian Voltorb is trying to be, and what we got is
so much better than any of us had guessed - it's actually a
perfect take on a Pokémon tied meaningfully to a Legends-specific game mechanic, rooted squarely in Legends-specific worldbuilding, in a way that only a variant of Voltorb could be
(what other Pokémon could possibly spawn as a direct consequence of crafting a Poké Ball??), and that's
exactly what I think a regional variant should be!
Also,
it is unbelievably charming and full of personality and the toy vibes are PERFECT
Hisuian Voltorb is my child
(maybe literally? we might be responsible for bringing them into existence all by ourselves) and I adore it
I cannot get over the fact that this absolutely bonkers team of designers took an idea I thought was all but inherently a waste of potential and would never be interesting
and said
no, look here, we're making another 10/10 variant instead, and you cannot stop us
The Pokémon designers working on this game have literally no chill and I am
here for it
As an aside, I love that every Pokémon and its type combination has been pretty reliably leaked by this point, and yet what we have is such a surface-level understanding of each of them - in a game that constantly insists on proving just how much thought goes into every one of its Pokémon - that we still basically have no idea what to expect at all, and each and every one of them could be a beautiful little surprise like this no matter how much we think we have its number
