Are you figuring the event out now,
Npixelz ?
If you follow the hints it is easy to get all the days event items.
Plus you get WING currency for the diamond shop or to spend on extra event turns as part of your rewards.
Remember the flower shop changes prices every two hours.
If you find salted eggs for 1 then ALWAYS buy those, they are going to give you the most return. You can save them to your backpack & use them to sell back on the same stall if the prices change, It's like getting an extra move.
