It's Busytown Day, and a delighted Hilda, and a not so delighted Huckle are chosen as King and Queen. They will have the honour of riding on Mr. Fixit's fabulous float. Hilda's got her own ideas of what the theme should be, and they're not the same as Mr. Fixit's. And when Huckle gets sick it looks like the parade's over... until Lowly pulls it all together and the parade is a success.
