"Greta is allergic to animals so she decides to have a cloud as a pet. She even puts a collar on it to take it for a walk! Having a pet cloud has many advantages, like helping neighbors water their gardens or putting out fires... But not all Greta's neighbors are happy with her choice of pet... Some are fed up with having their barbecues ruined and always having to take umbrellas with them in case they meet Greta and her cloud. The town is divided. Will they find a way to come to an agreement"?--
