Wowee Pinkfong Baby Shark Plush Singing Cube Yellow with Tag

Wowee Pinkfong Baby Shark Plush Singing Cube Yellow with Tag Still has original Tag The Back compartment where the batteries or voice box is, is still sewn shut, so I can not test it to see if it works or makes noise Since I cant open the back pouch, I do not know if it needs batteries and if it does, what type of batteries it will need Good preowned condition, normal signs of play wear, no major flaws, gently used Thanks for looking, please let me know if you have any questions
