Yo Mama! frozen yogurt will give away free frozen yogurt from 11 a.m. to 4 p.m. on Saturday, Aug. 13. The event serves as the shop's grand opening celebration.

Attendees only need to bring a new, unopened toy to donate to the Ronald McDonald House of Milwaukee to receive a voucher for a free small yogurt.

Yo Mama! will also offer an inflatable obstacle course for children, face painting, giveaways and other fun activities for the whole family.
