Knitting Barrette (とっとこあみあみ! ポニーテールちゃん) is the 133rd episode of the Hamtaro anime series.
The Ham-Hams meet Barrette, a hamster who can knit. Barrette has a crush on Hamtaro and she sees Bijou as a rival. Meanwhile, Penelope is sad that Pashmina is not with the Ham-Hams. Will Barrette be friends with Penelope?
Hamtaro notices that it had snowed outside, and goes out to play with the Ham-Hams. Once outside, Hamtaro notices a new hamster with Oxnard. After she loses control when riding a ball of wool, Oxnard introduces her as Barrette. From standing in the snow for so long, Hamtaro catches a cold; Barrette proceeds to wrap him up in wool, and kisses him on the cheek.
In the Clubhouse, Barrette announces that she has formed a crush on Hamtaro; to which she is told by Howdy that Bijou already fancies him. She instantly forms a rivalry against Bijou, stating that she will knit for Hamtaro all the time. In hopes of stopping the feud, the Ham-Hams decide that they will go out and play in the snow. Boss recommends that Barrette should play with Penelope, as Pashmina has other stuff to do.
Outside, the Ham-Hams are playing whilst Barrette and Penelope sit out and talk. Missing Pashmina, Penelope starts to cry. Barrette, to calm her down, makes some plush fruit and seeds; but afterward, Penelope wanders off. Barrette follows as she has to keep an eye on her.
The Ham-Hams started to build a sculpture out of the snow; but a strong storm picks up, so they take a break. When finding shelter, they realize that Barrette and Penelope are missing. Hamtaro, Boss and Oxnard search for the girls, leaving Maxwell in charge of protecting the other Ham-Hams.
The girls had fallen into a pothole. In order to keep Penelope calm, Barrette makes a plush Pashmina for her to keep, so she wouldn't get lonely. Oxnard notices wool submerged in the snow, and follows it to find the girls safe inside of the pothole. The three Ham-Hams work together to rescue the girls.
When arriving at the shelter Maxwell had found, the storm picks up even more and they all head into protection. The sculpture was too weak to hold and starts collapsing. Barrette creates supports using her wool around the sculpture so that it wouldn't fall. This works and the storm dies down. The Ham-Hams finish the structure and Pashmina arrives, wrapping Penelope and Barrette up in her scarf for warmth.
To thank all the Ham-Hams, Barrette makes plush hamsters for all of them to have!
