Monster Beach - Season 1 - Eps 45: Rain Damage
When everybody forgets Dr. Knutt's birthday, he bewitches the weather and Jan and Dean realise they must right the wrong of the forgotten birthday or face a damp and stormy future. Trouble is, making it up to the most demanding and self-centred monster on the entire island is quite a task. What does a miserable megalomaniac like Knutt want for his birthday anyway? The answer: utter misery.
