This is Toxica. She wreaks havoc on the environment in a popular children’s tv show called the Haz-Mat Attack Pack. When a young boy gets the Haz-Mat Attack Pack computer game, some pretty wild things happen. He and his friends learn about what it takes to clean up an environmental mess.
I was lucky enough to illustrate this book and it is now available for purchase. If the first review is any sort of harbinger, it seems like it will be pretty popular! It was great to combine my interests in art and the environment.
