Berti is homesick on her first day of kindergarten; Radish tries to prove that he's a great explorer by finding all the stickers for his classroom passport.

Berti makes a self-portrait but can't decide whether to give it to her Mami or Papi; Rose rests in the Chill Zone, but her friends worry she'll miss all the kindergarten fun.

The kids spin a wheel to get a classroom job, but Berti doesn't like the job she's assigned; when Albert, the class guinea pig, goes missing, the kids look everywhere for him.

Berti doesn't want to get her new sparkly sneakers dirty, so she refuses to play at recess; Berti loses her scarf at school and then spots it on a second-grader.

Berti doesn't want to donate her favorite book to the class book drive; Ms. Moreno lets the class turn a gigantic cardboard box into whatever they want.

Berti and Radish pretend to be twins for the day; Jamil is "Student of the Day," but he doesn't have time to fill out his poster because all of his friends need his help.
