Squishable makes these fairly big stuffies.

Steph gave me a squishable tortoise for Christmas 2009. Discontinued now but my favorite because it looks good and he's soft and warm. I don't use him as a pillow, more like a huggable sleeping companion.

I bought this other squishable turtle which is also discontinued. It's a bit too cartoony and still very round since I don't use it much (my main turtle is a bit flatter but still not flat; still good after almost 13 years).

I also have a mini squishable sea turtle which are more hand-sized. I don't particularly like the spots -- a bit creepy sometimes.

Anyway, these are great gift items or for your own use.
