Billy is having a party at the petting zoo - there are baby goats to feed, ponies to ride and lots of yummy party food to eat. But when Holly and Rose arrive, the picnic table has been destroyed. Oh no, the Party Poopers are here...Luckily the teeny-tiny Little Sparkles have arrived, too - Tikki the yellow kitten, Peppy the light-blue puppy, Bubbles the pink bunny, Princess the white pony and Tubbs the rainbow-coloured turtle - and they're going to make the party perfect!
