I hate pricking the bubble itself- seems t always leave a hole. lynnieb is right- a cold air bubble that it trapped will enlarge as it warms up. Give it a different place to escape: a thin skewer down the center top of the cake, all the way to the cake board, and remove. I take a fondant smoother, run it over the bubble, and it disappears like it was never there. The air found a different escape route.
