The Oinker Sisters are a trio of pigs who have appeared on Sesame Street periodically since Season 17. Their name is a riff on the Pointer Sisters (who had previously sang on the Pinball Number Count animated segments). The sisters are best remembered for their song "A New Way to Walk." The leader, Sooey Oinker, is voiced by Ivy Austin, while the other members have changed over the years. Singers have included Heidi Berg, Angela Cappelli, Cheryl Hardwick and Annette Sanders. Kevin Clash provided the voice for the lead sister in a brief appearance in the 1990 home video Dance Along!
