Your Tower of Sour carries over from garden to garden, so you don't have to retame sours in a new garden if you don't want to. The image on the right shows 8 glowing (activated) segments in a Tower of Sour. Featured from bottom to top: sour Shellybean, Sour Sherbat, sour Crowla, sour Profitamole, sour Macaraccoon, sour Cocoadile, sour Mallowolf, and sour Bonboon. Once you have completed the Tower of Sour with 8 pieces a Galagoogoo will be sighted near your garden.
