Art Challenge Sunflower is one of the 17 hidden mini-games that can only be accessed using a Cheat Engine. This mini-game is similar to Seeing Stars and Art Challenge Wall-nut, where the player must fill all outlined spaces with the respective plants. They must fill outlined spaces with Starfruit, Wall-nut, and Umbrella Leaf to make the shape of a Sunflower. The level lasts until the player fills the space.
