Roberta rescues tiny creatures. You know, the ones stranded in the middle of the sidewalk, upside down, flopping, or near frozen? A lot of the time, that earns her funny looks from kids at school. But one day there's an invasion of tiny creatures in her classroom, and Roberta will need to use her knowledge and creativity to show everybody that tiny creatures aren't so scary after all. They just need friends who rescue and understand them.
