level 19 ..
first you get the ball and put on the flower seeds
then you put on the hat
then you water it until the flower seeds dissapear
(which would only be the bottom half becasue the hat is on
once they dissapear take off the hat and your left with only
the top half covered in seeds, water it once
now put on the grass seeds
and water it once again
and thats it
if it doesnt make sense message me
