Roger has built a robot-lawnmower, which, for reasons of safety, is turned on and off with a secret password. While fine-tuning the lawnmower, Roger gets a powerful electric shock, which knocks him out. When he regains consciousness, he has lost his memory, he doesn’t recognize Fatou nor even himself. Total amnesia. Fatou is floored, at first she thinks it’s all a joke but no, Roger is definitely amnesiac. Right then, Junior rushes over in a total panic. He announces to them that Roger’s lawnmower is wreaking havoc with all the animals, mowing down everything in sight! They’ve got to stop it! Except that in order to do that...they need the password and only Roger knows it...er, knew it that is, before he lost his memory! Fatou tries every trick in the book to get his memory back...all in vain...
