Your objective is to earn at least one star before the time runs out. Like moves levels, they are relatively rare. There are only timed levels currently existing, making up % of all levels. They are actually moderately common up to World Six, but long appearance droughts will occur afterwards until World Twenty-Two. The distribution is also highly skewed, as most of them occur in the first 5 worlds. They are very rare after Sugary Shire, with a group of them in late World 8. However, since World Twenty-Two and above, these levels are quite common like the earlier episodes of the game.
