Alyson Hannigan costumes scarecrow

All dolled up as Mr. and Mrs. Scarecrow, Alyson Hannigan and hubby Alexis Denisof held on tight to their little pumpkin Saytana as they headed to a Halloween party, before taking part in some neighborhood trick-or-treating, in Brentwood.

The How I Met Your Mother star outfitted her darling 2-year-old in an adorable Jack-O-Lantern costume, complete with matching candy pail, black tights and orange Crocs.

What a sweetie!
