I want to find this childhood cartoon that i watch. The intro is always this boy going to a magical/town place behind a book gap and theres 4(?) main characters. It teaches us to spell words and solve mysteries. They also uses like an eye mask like superheroes ones when they are investigating a case(?)
They dress like normal kids,they change into superhero costumes i think but he did wore an eyemask. rather than being big its like they are tiny humans and it was like a small world behind the book in the library. He need to take out the book and it shows the world behind it,the camera starts zooming in and Op starts from there. For the spelling theres usually a missing words ect C?MER? and it waits for a few second so we as audience can answer.
I feel so bad for the poor girls :c
