'This fun, funny and affirming series will entertain children of all ages. In each book we are introduced to a new Mooper – Musical Markus, Nervous Nellie, Dramatic Dom and Giggling Gertie. At first they seem to have a really silly trait – Markus loves to sing…all the time, Nellie is always nervous, Dom is overly dramatic and Gertie just can’t stop giggling – but it’s these very traits that eventually transform these Moopers to superhero status!'
