Every morning, Abuelo walks Sofia to school...until the day that Abuelo hurts his ankle at a local landfill and he can no longer do so. Sofia misses her Abuelo and wonders what she can do about the dangerous Mount Trashmore. Then she gets an ideaâthe town can turn the slimy mess into a park! She brainstorms and plans and finally works up the courage to go to City Hallâonly to be told by a clerk that she canât build a park because sheâs just a kid! Sofia is down but not out, and she sets out to prove what one kid can do.
