When Lola the fly finds a mountain of poop, she sticks her flag in it and declares, “This poop is mine!” She’s so happy she has her own pile of poop… until Fiona the fly lands on her poop and declares, “This poop is mine!” Lola and Fiona have the battle of a lifetime as they try to decide who this poop belongs to. Who will win the fight for the big poop? Or can the two flies find some way to say, “This poop is OURS!”?
Though the Argentine illustrator draws his light-skinned, anthropomorphic flies so casually that he sometimes forgets how many legs they’re supposed to have, he gives the pair stylish eyes that look like outsized sunglasses and comically irascible expressions (they’re still scowling even as they lie in bed holding hands in the penultimate scene). That ill humor adds a piquant whiff to a parable that falls otherwise on the bland side despite the redolent mise en scène.--- Kirkus
"(...) does offer a humorous look at the possibilities of collaboration even over unpleasantness. With its close up views of the pooper (a dog), the flies and the poop, the (watercolor and pen?) art is fun and unfussy, suiting the subject.---Youth Services Book Review
