Harry the Hippo wakes up one morning to discover that his beloved mudbath has completely dried up, leaving him feeling disappointed and restless. Determined to find a new place to enjoy his favorite muddy fun, Harry embarks on a squishy adventure through the jungle. Along the way, he encounters various challenges-a puddle already occupied by froggy musicians, a tricky quicksand patch from which Ellie the Elephant rescues him, and a mysterious map from Max the Monkey that promises the location of the legendary Ever-Muddy Pool.

With his friends by his side, Harry braves jungle jumps, wiggly vines, and even a stinky swamp shortcut, learning valuable lessons about patience and teamwork. Finally, they reach the Ever-Muddy Pool-a perfect, warm, and delightfully squishy mudbath. The story culminates in a joyful splash party with all the jungle animals celebrating together. Harry returns home happy and fulfilled, his heart full of friendship and the comfort of a true muddy haven.
