The Nuclear Pea shoots peas that hit the zombies with a nuclear radius (Cherry Bomb). It is very powerful, as it also releases radiation, killing zombies and plants alike. It costs 350 sun, and first appears in PvZ II in the Giant Pool.
"He's scary. He's mean. He's nuclear! He's NUCLEAR PEA!! 'I'm just like that,' he says 'but I was born in toxic waste in the Bermude Triangle with sharks circling around me and stuff. My birth was pretty simple."
