The trio of electric cheeks dressed up this year for Halloween as you might guess, Hamtaro characters!

Nise on the left as Bijou, since he can change colors albeit not quite 100% with the ears still being green.

Sparks in the middle as Penelope, a simple yet effective cosplay.

Yarn as Pashmina, wearing a hoodie and scarf resembling the character.

Sparks fills up on all the candy from the bowl as he does usually while Nise isn't impressed and Yarn is too busy to care.
