The Rare Flower is one of the sacred items that Zeus asked you to find to save Poptropica and to become immortal.
How to get the Rare Flower
Go left and over the bridge to the Garden of the Sphinx. Your goal here is to get the water in the channel to flow to the dying flower by using the switches and gates up above you. When you’re done, collect the flower, which is your first item. While you’re here, jump up above the Sphinx and get the pomegranates from the tree.
