This is where the Teletubbies shockingly discover that their Magic Windmill has disappeared without a single trace...
And they cry and mourn over the windmill's disappearance, only for it to come back for a new Magical Event for them to watch... (and plus, it's four minutes long, you know that.)
And then, after the water rises (in which Tinky Winky thinks they'll see the Three Ships, when he is wrong) they see a group of yellow ducks with red (or orange) beaks, swimming around the magical ocean, where the Three Ships have sailed there.
