Three Fights With Skeleton Demon was an area in Plants vs. Zombies: Journey to the West and later in Plants vs. Zombies: Great Wall Edition, and was the second world exclusive to the former's Adventure Mode. It took place on the front lawn of a house in a small village, which oversees a cemetery full of zombies.
This area was similar to Night as mushrooms were awake and no sun fell from the sky. However unlike Night, there were no graves and only the first five columns of the lawn were muddied and could not be planted on, with the middle row requiring Flower Pots to be planted on.

This area is easily one of the hardest in a whole franchise, due to a critical lack of space. Most of instant-kills and Spikeweed became useless here. Using Doom-shroom is also highly not recommended because of crater he leaves. Overall, treat this area like Night with additional limitations.
Carrotillery is really useful in this levels, as his advanced rockets can be launched at unsodded tiles, reducing the need for protective and explosive plants. As a measure of defense, it makes sense to use a Pumpkin
Among the hero plants, Pig Squash is a good choice, as it has sufficient durability and serves as instant-kill. Nut Wujing and Iron Man Nut can be helpful too. Other heroes have no protection from being eaten, but still remain powerful. Note, that Hero Plants can stand on unsodded tiles
