Mercane and dohwar merchants who come into possession of a healthy gadabout might sell it for 2,500 gp or more.

This was already present in Spelljammer lore, from what I can tell. 

So this is pretty much the Spelljammer equivalent of an EVA spacesuit? I like it! Very flavorful, and I can see why they are highly valued. 

I can't help but think there's a bunch of questions about what happens if you're attacked while wearing of these. Can an attacker target the gadabout while you're wearing it, thus leaving you exposed in space when it's low health is one-shotted? If someone targets you, what are the odds of damaging it instead? And that's not even factoring in AoE spells that are pretty much guaranteed to kill this thing.

I feel like those situations should be addressed in the stat block, but as a DM I would probably tie their health symbiotically to the relevant player. Solves a lot of issues.

 Agreed. I'd rule it as a sort of living armor. If worn by a humanoid creature, the Gadabout cannot become the target of an attack. It should also have effectively 3/4th cover from non attack damage sources (ie Fireball and such)

Going to modify it for a spice-of-life game I'm running. I'm giving it 3/4 cover when flying, and full cover when not flying (The wearer can use their normal walking/swimming speed with the wings retracted, and they are no longer grappled)

It would be interesting to have pirates try to target the gadabout specifically during a raid or try and take them as part of their tactics.

Considering how valuable these things are, I'd say they'd rather target the humanoid wearing it, and try to capture the Gadabout for either selling or their own use

"The gadabout’s leaves even provide a nourishing syrup that its wearer can consume in the absence of other food and water. One Humanoid can survive on these leaves for up to sixty days."

I don't understand what this is trying to convey. Does it mean the gadabout runs out of sap after 60 days, if so why doesn't it explain how it generates more. If it means that the sap isn't nutrient rich enough to sustain you indefinitely how does that work? Because, if we are to be pedantic, assuming the sap cant sustain you indefinitely there wouldn't be some hard cut off. You would grow sicker and sicker (gain exhaustion) as time went on.

The fact it specifies one humanoid implies it means the former, but that still doesn't answer how the thing gets more sap. 

It could be as simple as if it's being worn/used it can't regain it's sap due to the energy it uses while flying. Maybe for everyday it isn't worn and has suitable sun and water, it regrows enough leaves and sap to sustain one humanoid for a day

I would surmise, since it isn't specifically described, they are leaving the specifics of that up to the DM.

Yep, this was part of MC9. The Elven Imperial Navy outfits their Marines with them for boarding actions.

In RAW terms since it's a separate creature it can be directly targeted, however with the way it wraps around another creature you could argue that that creature is providing at least half cover, though that won't help much against areas of effect (even a weak blast will probably kill one of these on a successful save).

I'd say most DMs will just ignore it and treat it as a worn item once attached, in the same way that most DMs ignore carried familiars and the like rather than forcing you to spend an hour summoning it back because it got caught in a blast. It'd be a pretty dick move for a DM to allow players to be left stranded in space without oxygen or any means of propulsion.

I had totally misunderstood the artwork and thought it depicted a Gadabout itself, a humanoid plant. It took a couple of times reading the stats to catch that the picture is of a person carried by a Gadabout. 

Just posting in case anyone else missed it.

 It also states that the creature requires water and sunlight to survive.  The implied context is you are stranded in space or traveling through space with just the gadabout.  So in that context, where it can only receive sunlight and the character is subsisting off the gadabout, it's leaves would sustain the character for 60 days before both the character and gadabout would be starving.

Do people bid for these things, or is it a preset price?

"Elves are the only Humanoids to date who know how to grow gadabouts. Since gadabouts don’t generate seeds, each one is a valuable commodity. Mercane and dohwar merchants who come into possession of a healthy gadabout might sell it for 2,500 gp or more."

I think because it is a plant, it only gives off 60 days in total, then dies afterward?

Which part needs an edit?

 There isn’t anything wrong with the sentence.  If you’re referring to the name “Mercane,” I’d wager it’s probably the updated incarnation of the Arcane from classic Spelljammer since that original name is about as clever as calling an ancient civilization “the Ancients”
