Pulling Together

Grandma knits Lila a poncho.  This poncho has not one, but three, head holes in it! Lila is sure Grandma made a mistake. Grandma sends her out to play, saying, "We all pull together!" Lila thinks that makes no sense. She encounters three kids who need her help, including the neighborhood bully. Who will she help? And what does the poncho have to do with it? and make the world a better place?
