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.
