-In the Max%, you need to max 34 ducks, That will be at least 3 1/2 hours, be prepared -You need 5,050 coins to buy every item -For energy you can do a glitch where you buy at least one seed and ram your duck against the wall, and keep your cursor on the edge of the window, the duck also needs a hairstyle for this to work. (A hat might work but that is untested)

-Before the run grind out like 6,000 coins from a new file, then when you start the run, skip the tutorial by clicking the bottom right. You will keep all of your money. -Buy the 5 eggs from the running shop -Max out all the levels and complete all the races. (Don't forget hats) -After you beat the Champ, keep buying the eggs in groups of 6 until you finish all of them -The recommended order for grinding levels is Swimming(In case of NaN just buy the same egg again),Jumping, climbing, flying, running, energy -The thing that causes NaN in swimming is skipping past the space press to start the swimming 2 game
