Superjuffie takes action!

Miss Josje seems like an ordinary teacher, but there is something special about her. When an animal is in need, she turns into Superjuffie! It is summer vacation and Miss Josje is looking forward to a few lazy weeks. Then it turns out that the mayor has plans to renovate the City Park, where her house is located. He wants to replace the 200-year-old oak tree with 'New Nature'. The mayor is very proud of this technological feat. Although this fake nature is almost indistinguishable from the real thing, Superjuffie soon discovers that it is poisonous. She has her hands full saving animals that have accidentally eaten it. How can she prevent the plans from going ahead?
