Here are the two red panda plushes I'm familiar with:

Aurora World Miyoni Red Panda Plush

Great fur and appearance, although the back of the ears aren't black/brown like a real panda. Has one of the best looking panda tails I've seen on a plush, although it's a bit short and stiff. The plush is in a firm sitting pose and isn't floppy, which makes it good to display but not as ideal to cuddle.

Wild Republic Red Panda Plush, Cuddlekins, 12 inches

Less realistic looking but very soft, floppy and huggable with a nice long tail.
