No, it isn't weird. Around one in five plush toys sold in the US now goes to an adult, and that number has been climbing since the pandemic. The question people are actually asking is a different one: will this particular adult like it, or will it land wrong?
That depends on who they are and what you put with it. This article covers when a stuffed animal works as a gift for a grown-up, when it doesn't, and the one thing that turns it from a toy into a message.
The short answer: adults buy plush for themselves now

In 2024, 21% of plush toys were sold to adults over 18, according to Circana's US toy industry adviser, as reported by CNN. A survey commissioned by Build-A-Bear, cited in the same report, found that more than half of adults had kept a stuffed animal from childhood, and roughly 40% sleep with one.
So the person you're worried about is more likely than not to already own one. The stigma is mostly in the giver's head, not the receiver's.
That said, "most adults" isn't "this adult." The rest of this is about telling the difference.
When a stuffed animal lands as a gift
It works when the plush is carrying something. A stuffed animal on its own says "I thought you were cute." A stuffed animal with a reason says "I thought about you." The second one is what people keep.
The reason usually looks like one of these:
They're going through something. A rough week, a breakup, a diagnosis, a move. Something soft that sits on the nightstand during the hard part is a different gift from a candle.
They're far away. You can't drop by, and a text disappears. A plush on their desk doesn't.
Something good just happened. New job, exam passed, first apartment. Flowers die in five days. This is still there when they're settled in.
There's no reason at all. Which is the best reason. "I saw this and thought of you" is a whole gift.

Notice what all four have in common: the plush stays. It sits somewhere they see it. Weeks after the card has been read, it's still on the shelf, and every time they look at it, it's the day you sent it.
When it doesn't work, and what to send instead
Be honest with yourself about three situations.
They've told you they don't like cute things
Believe them. A plush here reads as "I didn't listen." Send something they've actually mentioned wanting.
You don't know them well yet
A stuffed animal from someone you've met twice carries more weight than you mean it to. Wait until there's a memory to attach it to.
It's a joke gift
Novelty plush get a laugh and then get shelved. If the point is the laugh, fine. If you want it to stay out, pick something they'd want to hold, not something that's funny once.
Everyone else, which is most people, is fine.
The note is what makes it not weird

Here's the part that decides it. The plush is the object. The note is the gift.
A stuffed animal with nothing attached leaves them guessing what you meant. A stuffed animal with one honest line on a card removes the guessing entirely. They don't have to wonder if it's a joke, or a hint, or a mistake. It says what it is.
You don't need to write well. You need to write one true thing:
"Saw this and thought of the Tuesday you drove out to help me move. Still owe you."
"I know this month has been a lot. This one's for the nightstand."
"No reason. You've just been on my mind."
Short beats long. Specific beats sweet. One line beats a paragraph.
