Ulu's father bought her a chemistry set, so she could be like her father. He buys the set from an odd man who has a dog with six legs. She wants to clean the rivers, but her experiment creates the smell of farts. Mushrooms sprout from the floor. Yams walk around. Dogs shrink. Ants talk and explode. Ulu has to stop the craziness, but the houseplants, like octopi, attack.
A delightful YA tale of comic zaniness.
