Emek and Luna followed a parade path marked with balloons. The balloons repeated in a pattern: green, green, purple, orange, green, green, purple, orange. At the next sign, one balloon was missing. They looked back, found the repeating pattern, and chose an orange balloon for the empty spot. The path was correct again, so they happily followed the balloons and arrived at the cheerful parade celebration.
