It's a ride-on, bouncing dog toy. It's used the same way as a Rody. The size and functionality are about the same. My child loved it and enjoyed playing with it, so there are some stains and scratches (please see the photos). I think it can be played with without any problems, such as how to inflate it. It has been disinfected with alcohol. It will be shipped deflated and compressed. An air pump is not included! You can easily inflate it with a balloon air pump, which can be purchased at 100-yen shops. If you understand that this is a used item, please consider purchasing it. I have set a longer shipping period. If you are in a hurry, please comment before purchasing.
