Grandfather's Birthday

Grandfather Flump got up rather late today. He is the last to finish breakfast. He suddenly remembers that it is his birthday today. There are no presents, no cards and no one has wished him a happy birthday yet. Everyone must have forgotten him. He decides to go and jog their memories. Mother Flump is in the kitchen and Grandfather Flump tries to find out if she is baking anything special. Mother Flump avoids the question and gives him the impression that she does not know what today is apart from being tomato soup day. He goes away and finds Perkin. Perkin is making a picture for Grandfather Flump. Posie sees him coming and quickly takes the picture away. Grandfather Flump tries to see if Perkin has remembered but goes away disappointed. He next finds Posie, Father Flump and Pootle but none of them give the game away. Has no one remembered his birthday?
