Hamtaro

On Laura’s first day of school, Hamtaro can't help Laura choose the perfect outfit, but he decides to help by keeping an eye on her at school. He soon gets sidetracked though when he runs into his new friends Oxnard and Boss, who introduce him to more hamster pals, Pashmina, Penelope, Howdy and Dexter.

Since the opening of the Ham-Ham Clubhouse, Hamtaro is meeting new hamsters every day. Pashmina and Penelope introduce their friends Maxwell, Panda and Sandy. Cappy also sneaks up on them under a saucepan, and they become friends. But with all the new Hamsters come Ham-personalities that clash. One day when this happens, a fed-up Boss kicks everyone out the clubhouse.

Boss is cleaning the Clubhouse to invite Bijou over. He, Hamtaro, and Oxnard go visit Bijou to persuade her to come. She refuses, because she has never been outside of her cage, and her owner would be worried when she finds out she's gone.

One day, while listening to Laura and Kana plan an evening barbecue, Hamtaro becomes enchanted by what the girls are eating--a sparkling candy called “Diamonds of Sugar”. Puzzled, Hamtaro goes to the Ham-Ham Clubhouse to ask his friends if they’ve heard of these "diamond things". After many theories from the hamsters, Boss insists the candies come from the sky and are best seen at night.

Laura's parents take her on her first trip to the beach; but when they tell her that the water can be dangerous for hamsters, she decides not to take Hamtaro. However, Hamtaro and the Ham-Hams have other ideas! They want to see the ocean, so they make a plan to go to the beach too, after agreeing that if they stick together, they can look out for one another.

It's a summer festival! The Ham-Hams learn from Maxwell that on the night of the festival, flowers (fireworks) will appear in the sky. Pashmina separates from the Ham-Hams to find the flowers.

Hamtaro goes with Laura and her family to visit her grandmother in the country. The Ham-Hams are excited for Hamtaro, because Grandmother's house is surrounded by sunflower fields.

After Laura begins a new semester, the Ham-Ham pals start to wonder if they might be missing something by not going to school. After Hamtaro, Oxnard, and Boss sneak into Laura's school for a day to check things out, the Ham-Hams set up a separate school of their own.

Laura's father asks her to deliver an important floppy disk to his office. While Laura packs her bag, Hamtaro gets trapped inside. On the way to Mr. Haruna's office, Hamtaro picks up two hitchhikers, Oxnard and Penelope, who have just escaped from an angry crow. When Oxnard's sunflower seed falls to the ground, Oxnard jumps out of Laura's bag to go after it, and Hamtaro and baby Penelope follow, not knowing that the yellow disk has slipped out of Laura's bag too.

It's Grandparents Day, and when Grandma comes for a visit she shows Laura an old clock that she and her friend, Kaitlyn, bought years ago. Laura is touched by the story and decides to surprise her grandmother by trying to find her long-lost friend for her.
