Alyson Hannigan and her family go for an Irish Leprechaun theme for their Halloween costumes while trick or treating on Thursday (October 31) in Brentwood, Calif.

The 39-year-old actress and her husband Alexis Denisof were both dressed as leprechauns while their four-year-old daughter Satyana was a rainbow and their 17-month-old daughter Keeva was a pot of gold. So so cute!
