Level 3-7 is the twenty-seventh level in Plants vs. Zombies, Plants vs. Zombies: Journey to the West, and Plants vs. Zombies: Great Wall Edition, and it is the seventh Pool level. It is a regular level. When this level is finished for the first time, the player obtains the Torchwood.
- The player has to deal with both Zomboni and Buckethead Zombie, which may be tough if they do not choose the right plants, since Zomboni appears only in the final wave.
- Required plants:
- Plant two rows of Sunflowers and Potato Mines for sun. Plant Potato Mines to fend off the first two to three zombies. Then, start to plant Repeaters or Snow Peas on land and Wall-nuts evenly on each pool lane two columns in front of two columns of Snow Peas or Repeaters. Then, place Spikeweeds on every other spot on land.
- Depending on your preference of plants, you may find the Repeater redundant when you get the Spikeweed. If so, plant a column of Snow Peas (two on land) and on the rest plant Spikeweeds to maximize damage.
