You must go through the pantheon of the stars atleast once and defeat the host first. Be sure to break the wall that leads from the room with the ball to practice the juggling game (top left of room) to the end area with the last 3 game rooms (pretty much a crouched tunnel with a planting location at the end in a tiny room). Mushishi is your best friend! MAKE SURE! any walls you broke totalling to 3 now have plants growing there (prevents the walls from coming back after map is reset). Once you return later on you will take that pathway you filled with plants AVOID ACTIVATING ANY GAMES IN THE PANTHEON ASIDE FROM LAST ONE! You cannot avoid the last one. You will need 1 fruit or guts to get the enemies below to drop there force fields so can slide by to the last game. Hide and once sanitation begins go down and break the blocks to get through (not a pacifist trophy, you can have your sword). Grab the wildling seed below the next room (hidden, but easily findable) go to host and he will ask you to plant the seed. You're welcome! I tried EVERYTHING! For such a simple solution
