Thanksgiving Week is a yearly event, first introduced in 2017, revolving around Thanksgiving, a national holiday celebrated in Canada and the United States. It was first introduced on the 23rd of November, 2017.
During the 2017 event, a building challenge was introduced where players could receive exclusive trophies by designing a Thanksgiving-themed world and uploading the render onto the forums here or, by posting it on Instagram using the #ThanksGrowtopia hashtag.
