Roblox Imagination (2018) was the third annual Imagination event sponsored by Netflix's Next Gen. It began on September 6, 2018 and ended on September 20, 2018. There were three games and six prizes, divided into two prizes per game along with two exclusive catalog items. A grand prize was also featured.
The Momo Companion was unintentionally put on sale for a few minutes on the catalog for free. Only 2,514 players managed to purchase it and lack the task of earning it in the Fashion Famous game.
There was a glitch in Make a Cake: Back for Seconds!, where the player could get the Rainbow Wings of Imagination by making a cake with the 7723 topping and neon frosting, and then sharing it to the 7723 Companion in the Cafe, rather than finding three ingredients to make a cake and share it to the 7723 Companion.
