Tyler Skyspear. I have 6 characters, all with couch potatoes. I feel they are the easiest to garden. They provide you with 3 major pet snacks. 1. Captain Canteloupe 2. Fancy Yogurt 3. Golden Wheat They also provide you with enough tc cards and minor pet snacks to sell. I am always at max gold and able to train any pet fairly easy. They like the red barn, botanical garden, tropical gnome, litter and sandwhich station. The two latter are a bit difficult to get. As the sandwhich station is a crafting item that takes a LOT of grendleweed and the litter takes days to farm for. You can buy the couch potatoes in the crown shop or easily farmed in Grizzle. Bonus, if you are a member, KI does double farming rewards. Which has made me stocked full of couch potato seeds. Good luck and good farming :) P.S I left a link to Spud Farming. It'll teach you everything I may have left out. http://www.duelist101.com/other-w101-guides/w101-farming-guides/spud-farming-a-simple-way-to-get-mega-snack-plants/
