U-Turnip

U-Turnip is a plant in Plants vs. Zombies 2. It temporarily makes zombies on the screen face backwards, making them walk the other direction. If a zombie who is facing the wrong directions encounters a zombie going the opposite way, that zombie will go the wrong direction as well.

Zombies that go the other direction stop when they reach the 8th column.

Almanac entry
U-Turnip wants a better job. Shouldn't drivers know what a U-Turn is? But then again, those drivers are zombies.

Strategies
U-Turnip is similar to the Thyme Warp, and due to Thyme Warp being world-exclusive, U-Turnip is an alternate for him. It's very useful in Modern Day, especially if there are portals or Gargantuars.
