Once, there was a Grump . . . While rolling along, a Grump encounters a Blade of Grass, a Flower, and a Tree and tells them to move out of its way. But the Blade of Grass, the Flower, and the Tree can't move and ask the Grump kindly to move around them. But the Grump is too grumpy to do that. So the Grump eats them all up to nothing but quickly learns that grumpiness has dire consequences.
