Meet

The big kahuna, the head honcho, the belle of the ball, the top dog, the grand poobah…you get it. The Grumpopotamus is our co-main character, and all things Grump-O-Verse (more on that later) flow through him. Don’t tell anyone, but he is the real star of the show (sorry, Mom). Through the twists and turns of the series, he leads the kid in befriending the lively, funny, and sometimes mischievous characters that fill his world.

 

He is big, he always looks grumpy, he stomps loudly, and has an indiscernible sound he makes when he “speaks” (ala Perry the Platypus).
