Moon struck will prevent candies matching the colour on the left side of the moon scale from spawning. If blue colour appears on that side, eight additional candies have to be collected in addition to the 3 candies they have to collect three moves after the moon struck. This has to be repeated if blue colour appears again on that side of the moon scale.
The order is worth 12,000 points. Hence, an additional 18,000 points is required to earn one star.
This level looks like the erroneous level 276 in Dreamworld, but this level needs only 120 blue candies. It has fewer orders, making this level much easier than all versions of 276. Level 276 currently have not been redesigned to become a proper Dreamworld counterpart.
Unlike level 276, this is a proper Dreamworld counterpart of Level 281.
