Kids inflatable costume horse

My kids have outgrown this awesome inflatable horse costume. Best for ages 5-7. My 8.5 yo son is too tall for it. I clamped the ankles, wrists and collar so I could inflate it. From Morphsuits, discontinued. Paid $80 for it. Elastic ankles, wrists and neckline. The zipper goes around the low back. Kids legs go in the horses front legs. Back legs are just air filled. Easy to trick or treat in.
