The advert always had an animated polar bear trying to look cool while sipping his Cresta. I remember Cresta being much more frothy than fizzy, and it was a staple drink for kids when I was young.
The advert went something like this:
(A bear is talking to farm animals) Bear: Do you know what all the bears up at the North Pole drink when they’re thirsty? It’s the sea man — the Arctic Ocean! Now me, I’m really into this frothy Cresta — like this strawberry flavour. (Cows moo and chickens cluck etc.) The day they start making the Arctic Ocean in strawberry is the only day this young bear’s going to drink it! Voice-over: Cresta in five fruity flavours. Bear: It’s frothy man!
