Talk about cute! Alyson Hannigan embraces Halloween as she transforms her entire family into glittery seahorses

Alyson Hannigan should win for best original Halloween costume.
The How I Met Your Mother star and her family were a colourful sight as they combed a Los Angeles neighborhood on Halloween dressed up as seahorses.
Alyson, 38, obviously put a lot of thought and care into everybody's costume.

Horsing around: Alyson Hannigan and husband Alexis Denisof took their daughters, Satyana, three, and Keeva, six months, Halloween trick or treating and all went as seahorses

The former Buffy the Vampire Slayer star led the pack, wearing a glittering green and blue suit with tail and head piece over shiny blue leggings and a bright pink long-sleeved top.
Alyson's husband of nine years, actor Alexis Denisof, matched the actress's look by wearing a different shade of blue and green with casual blue trousers.
The children, of course, were the centre of attention on this outing.

Colour-coordinated: Alyson sure put a lot of thought into the family's Halloween costumes this year

Sweet treat: Alyson holds up a piece of candy to entice Satyana with

Losing something? Satyana's head piece appeared to be sliding off, but Alyson saved the day

Satyana, three, looked adorable in her pink-hued seahorse costume, and seemed to be having a ball as she carried her ghoulishly green candy basket.
The couple's newest addition to the family, six-month-old daughter Keeva, enjoyed the early evening stroll comfortably strapped in her seahorse harness, worn by Alexis.
It was now you see her, now you don't as Keeva's seahorse hat kept sliding over her little face.

All better now: Satyana looks thrilled to be able to see out from under her seahorse head again

So cute: Little Keeva, six months, got to ride in a seahorse harness and seemed to love every minute of it

Satyana seemed to be having the same wardrobe malfunction too.
Alyson seemed to be stopping a few times to adjust Satyana's head piece so she could see where she was going.
But it was all in good fun and Satyana was having too good a time to let anything get her down.
Satyana seemed to really enjoy one spooky, decorated house.

Peekaboo! Six-month-old daughter Keeva, enjoyed the early evening stroll, when she could see

It's candy time: Satyana filled her bag with treats
