Nearly 30,000 wiggle balls have been recalled by Toys R Us because infants can choke on the toy.

According to CNBC, the recall involves "Bruin Infant Wiggle Ball" toys, also known as giggle balls.

So far, there have been six reports of rubber knobs from the balls falling off, including four reports of pieces going into the mouths of children.

The recalled toys were sold at Toys R Us and Babies R Us stores in the United States and Canada from June 2016 through January 2017.

The product has the model number "5F6342E" printed on it.

Those who have the recalled toy should stop using it immediately and should take the product back to the store for a full refund.
