When Professor Bumble starts inventing, anything can happen — and usually does.

From flying shoes that zoom off without warning, to a bubblegum formula that makes bubbles bigger than houses, to a talking hat that won’t stop telling bad jokes, the professor’s workshop is full of wild ideas. But now, something strange is happening: every single invention is disappearing. And the professor’s only clue is… a trail of mysterious crumbs.

Professor Bumble’s Lost Inventions is a seven-day epistolary adventure where each letter reveals a new, delightfully silly gadget gone missing — and a new clue in the mystery. Who is stealing the inventions? And can the professor solve the case before their most important creation vanishes too?

Funny, imaginative, and full of surprising twists, this whimsical story is perfect for kids who love gadgets, laughter, and a bit of mystery. Join Professor Bumble and see if you can crack the case!
