Mattel Series Jurassic World Mega Attack! T-Rex. I'm selling this because my child no longer uses it. There are no major scratches, but to prevent any problems, I'm listing it as "slightly damaged." Please understand this before purchasing. It's a sound-activated type, and I've confirmed it works with new batteries. If you need them, I can include new batteries for an additional 100 yen. Please comment if you'd like them.
