Merve, the mouse, is very forgetful.
He loves to run about the house that he lives in, but it takes him ages to find his way back to his nest in the attic.
Will his Mummy and Daddy ever find him if he gets lost?
Will he frighten Miss Sillyfog, the owner of the house?
Will he get caught by Marmite the dog or Marmalade the cat?
What can he do to find his way back safely?
