Chilies, sunflowers, and carrots - for urban gardener Toni and her friends, the world can't be colorful enough. Toni loves her internship at the BioTop nursery. Her friends are less fortunate: Cora-Lee is stuck just filling cabinets at an animal clinic, Elif is bored at the tax advisor's office, and Adam hasn't even looked for a position. So, it's no surprise to Toni that the three of them gradually drop by the nursery to join in. BioTop is also in urgent need of help, as someone is playing ruinous pranks on them. Only a clever plan can save the flower paradise. The urban gardening adventures of Toni and her friends continue. Volume 1: Better cucumbers on the roof than tomatoes in the eyes. Volume 2: One for all, all for the weeds. Volume 3: Flower happiness to the power of four.
