Purchased at the aquarium. The inside of the mouth connects all the way through, so my child enjoyed putting various toys in it. I looked it up when listing it, and it seems you can put your hand in it and use it as a pillow. Please refer to the photo with the Plarail inside for the depth. The Plarail is only to show the length, so it is not included. As you can see in the photos, there are some slight stains, but personally, I don't mind them much. The teeth have a little bit of fuzz. Home cleaned. Other than that, I don't think there are any noticeable stains, but since I am a private seller, there may be oversights. It will be compressed and shipped in simple packaging.
