Inflatable, so cheerful and fun! I bought it for my autistic sons to vent their frustrations at. He’s also received lots of hugs and kisses too! We had a little sand leftover and used it to give it some weight so it doesn’t fall over. Us parents have also enjoyed boxing it a few times too!!🤣. I don’t know how we lived without our new friend dinosaur! 🦖❤️😃
