I have always loved the vintage pet plushies, and I think it would be neat as a pet color. I know there are several colors within the vintage, so possibly a vote to choose which one?

They are all adorable.

The idea in my opinion is too close to nostalgic as some species are very much so vintage plushie styles while others are just nostalgic toys. You could argue the toys they are based off of are vintage/classic.

Yeah this is pretty much the same as Nostalgic seeing as several nostalgic pets are already plushies/stuffed animals.

If there was a way to differentiate this from the already existing nostalgic pets then maybe it might work, but as it stands right now, the idea is pretty much a riff on the already existing nostalgic pets and therefore wouldn't work.

What about if the plush pets looked more bright/sparkling?

i love those plushies too but this exact suggestion was made years ago and was the catalyst for the nostalgic color to be created in the first place.
