The Sparrow Sisters, want to take a bath but their birdbath is empty and the fountain isn’t working. Gordon replaces the broken water pump with a brand new super-pump from Percy's Gnome shopping catalogue. Unfortunately, it’s so powerful it empties the entire pond! So, Gordon creates an ingenious water system that gets water from the tap at the far end of his garden to the pond, creating a fantastic water theme-park ride at the same time. Everyone has great fun at the new lido.
