Secret Plan of 4b: Funny school adventure for ages 8 and up

Something isn't right at Regelberg Elementary School. Overnight, strange new rules appear everywhere-rules that weren't there yesterday. Laugh only at 10:12 a.m.? Spontaneous idea detected → fill out a form? Deviation from the plan = mandatory paperwork? Milo discovers a secret note with a suspicious stamp. Fina knows immediately: this isn't a normal note. It's... official. And Turbo? He accidentally stumbles into a mystery that's supposed to make the entire school "perfect." But perfect is dangerously boring. When the three uncover the secret plan of Class 4b, one thing is clear: PROJECT PLAN-PACKAGE is already running-and the plan is writing itself! Now Class 4b needs a counterplan... one so wildly creative that no stamp in the world can stop it. A funny school adventure for ages 8 and up-with short chapters, big laughs, and tons of chaos, teamwork, and fun!
