So Thawful

Difficulty: Medium

So Thawful is an achievement in Plants vs. Zombies 2: It's About Time. It is achieved by thawing 13 ice blocks in a single Frostbite Caves level. It is worth ten points on Game Center for iOS devices.

Strategies
Despite the icon showing Hot Potato, you do not really need to use them only. Frostbite Caves - Day 2 is good for this achievement, since it involves the wind. 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 the second time, also bring Pepper-pult 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 9/13 (69%) of the ice blocks required for the achievement, then let the Hunter Zombies freeze your plants so you can melt the remaining 4/13 (31%) needed.

Trivia

 * So Thawful is a pun either on the phrase "So Awful" or "So Thoughtful".
