Manny and his pal Gertie stand up for the environment—because every superhero needs a planet worth saving—in this companion to Super Manny Stands Up! from New York Times bestselling author Kelly DiPucchio and illustrator Stephanie Graegin.

Every weekend, Manny and Gertie put on their capes to defeat earth-threatening dangers.

WE ARE MIGHTY!
WE ARE AWESOME!
WE ARE TOUGH!
WE ARE SMART!

Stampeding dinosaurs, ferocious lions, and snapping, snarling veggie monsters are no match for this Super Duo. But when Manny and Gertie come face-to-face with swarms of litter bugs in the city park, will they be able to call on their superhero smarts to stand up for their planet?
