| So Thawful|
Thaw 13 ice blocks in a single level
Difficulty: Somewhat easy
So Thawful is an achievement in Plants vs. Zombies 2. It is achieved by thawing 13 ice blocks in a single Frostbite Caves level. It is worth 10 points on Game Center for iOS devices and 1,000 XP on Google Play Games for Android devices.
Its name is a portmanteau of the words "so awful," referring to the frozen plants and the player trying to unfreeze them and word "thaw," meaning to unfreeze, which refers to the player using warming plants and Hot Potato to unfreeze the frozen plants. It may also be a pun on "thoughtful."
Despite the icon showing Hot Potato, you do not need to use them only. Frostbite Caves - Day 2 is good for this achievement, since it introduces frozen winds. You will also get six plants in ice blocks at the beginning. Bring the Hot Potato and its Imitater version as well, if you have it. If you are playing this level for the second time, bring Pepper-pult, Fire Peashooter, or any other thawing plant with you.
Frostbite Caves - Day 14 is also another good day for getting this achievement, as it has eight frozen Sunflowers pre-planted, a frozen Split Pea, and the Hot Potato and Pepper-pult already chosen for you. Simply melt the Sunflowers and Split Pea to get 9 of the 13 ice blocks required for the achievement, then let the Hunter Zombies freeze your plants, so you can melt the remaining 4 needed.
- The amount of ice blocks required to thaw may be a pun on number 13, which is often abbreviated to be an unlucky number.
