Calm Chuck (淡定恰客; pinyin: dàndìng qià kè) was a premium plant in Plants vs. Zombies Social Edition. He costed 75 sun and his ability was similar to Pumpkin, being able to encase plants in an edible defensive shell, but instead of being planted on just one plant, he was able to be planted on an entire column of plants similar to plants in Column Like You See 'Em.
He was available from June 25, 2012 through September 24, 2012.
- He was the last plant of the game to be unlocked.
- He, Super Chomper, and Last Star were the only three plants in Social Edition to be sponsored by a product.
- His almanac flavor text is a reference to the belief that the world was going to end on 2012.
