My twin 9-month olds, like all babies of that age, love to show when they're displeased by throwing something. When they try that with the Bendy Ball, most of the time they forget why they got upset.
This cute thing can be bent while holding and you can put your fingers inside it. Plus the ball inside that you can't quite get out has a little ball inside it that sounds like a bell almost. If you want to throw it to show your displeasure at something, you'll end up putting your fingers into it first. Those distractions are priceless.
By the time baby finally rolls this ball, it is with a positive frame of mind, and she wants it back to try again.
I can see that this durable little toy is going to be used in many ways and constantly. It's a lot of fun to roll their way and see how they try to figure out what to do with it.
Beyond that, the colors are great. The 5 outer caterpillar parts on diameter are cute. I think this is an educational toy that teaches about hand manipulation.
