Alyson Hannigan and Family Go Trick-or-Treating as Matching Seahorses (GALLERY)
Alyson Hannigan and her family -- husband Alexis Denisof and daughters Satyana, 3, and Keeva, five months -- celebrated Halloween the cute way on Wednesday by dressing up as matching seahorses, complete with lots of glitter and lots of "Aww!"'s
The family was all smiles as they trick-or-treated in and and around Los Angeles -- and rightfully so, given how adorable their costumes looked.
"Gotta go get some glitter makeup for tonight!!!!" the How I Met Your Mother star tweeted early Wednesday morning.
Hannigan and Denisof welcomed little Keeva earlier this year, on May 23.
