Some Grumps Have Bumps

Meet the Grumps—tiny, colorful friends from the Land of Grumpy… who are not grumpy at all! They’re cheerful, curious, and always ready to play. In Some Grumps Have Bumps, children will follow these adorable little characters as they head to the playground for a day packed with giggles, wiggles, and big-hearted fun.

The Grumps come in bright colors like blue, green, and red—and some Grumps have bumps that little readers can count along the way! As the Grumps climb, swing, slide, spin, and play, preschoolers get gentle practice with early learning skills in a way that feels like pure playtime. It’s a joyful read-aloud that invites kids to participate: count the bumps, spot the colors, name the playground equipment, and predict what the Grumps will do next.

Beyond the laughs, this story also supports important social-emotional growth. The Grumps model friendly playground behavior—taking turns, playing together, sharing space, and enjoying group fun—helping young children learn how to socialize with kindness and confidence.

Perfect for story time, classroom read-alouds, and bedtime laughs, this playful picture book is a celebration of movement, imagination, and friendship—because even if you’re from the Land of Grumpy, you can still be happy, silly, and full of fun!

Best for ages 3–7 (Preschool through early elementary) Great for: counting practice, color recognition, social skills, and read-aloud fun
