The LEGO Day marathon was an 14-hour marathon event that occurred on Cartoon Network on December 13, 2015, from 6AM to 8PM. As the title implies, Cartoon Network aired nothing except LEGO programs all day, including the Mixels special "A Quest for the Lost Mixamajig." The event was made to promote the sneak peek of Nexo Knights that aired that day.
