You should be able to use a flat screwdriver or the side of a small coin. I purchased this product as a gift for one of my nieces. I don't recall what I used, but I believe I was able to remove the battery compartment with a small flat screwdriver. Hope this helps.
I'm not sure if the paws are stamped or if the fabric is dyed with the pattern. So far they seem very durable, no wear at all after 10 months. (And the lullaby paw gets a workout!) While the paws aren't embroidered, the eyes, nose, mouth, and hearts on the chest are.
I have 2 grand children that own a scout and a violet(I believe that is the puple one). Their names are Magdalena and Elijah and they say both their names. I will double check with my son and see if he can find the answer for you. I hope this helps, so far.
