Rosie finds out it's Abuela's birthday and prepares a birthday party in a box. She will send it all the way to Mexico! But how will the package arrive? Will a wizard take it? Or maybe . . . a mouse? Rosie and Gatita learn about the postal system and all the supertastical work behind mailing a package. Happy birthday, Abuela! - A book based on the hit PBS KIDS® show, Rosie's Rules. The show is nominated for a 2025 Emmy in the best preschool animated series category. - A great way to encourage children to build relationships with family members that live far away from them. - The perfect ode to all wow-mazing grandmothers out there and a delightful story to foster the bond between children and grandparents! Great for shops that sell children's books, kids' bedtime stories, picture books for toddlers, educational books for kids, fun stories for children and books based on media tie ins and PBS properties.
