Sun Bombs

Sun Bombs is a Brain Buster in Plants vs. Zombies 2 unique to the Far Future. In this Brain Buster, falling sun is replaced with destructive purple sun. If the player taps the sun while it is still purple, it will deal 25 normal damage shots to any zombies and destroy any non-defensive plants in a three-by-three area around it, while defensive plants deal damage. When the sun falls all the way down, it will turn into normal sun. Sun-producing plants besides Sun Bean and Toadstool cannot be used in these levels. It is played in Far Future - Days 4, 19, and 24. After it touches the ground, it will turn into a normal sun. Like normal sun, it disappears if not collected quickly.

Sun drops from the sky far more often in these levels, and it is up to the player whether they want to collect the sun, or use it as an attack towards the zombies. It is very useful for hordes of zombies that are attacking the plants.

Trivia

 * Currently, Sun Bombs is the only Brain Buster that focuses on sun.
 * If the player keeps collecting the Sun Bombs, a message will say "Wait until sun falls to the ground to collect it".
 * It is possible that the sun is purple while it is volatile because purple is the opposite color to yellow in the RYB color model.
 * If the player triggers a Sun Bomb to destroy a Robo-Cone Zombie, he or she will get the Sun Damaged achievement.
 * Unlike the normal levels, this is the only Brain Buster where in sun falls more constantly than the original levels and its Endless counterpart.
 * Sun Bombs seem to glow slightly more than normal sun.
 * This is the second world-specific Brain Buster that lets the player choose their plants. However, sun producing plants are not allowed. The first is the Powder Keg from Kung-Fu World. The third is Dark Alchemy in Dark Ages.
 * Despite sun-producing plants being banned, Sun Bean, Toadstool and Gold Bloom can still be used.
 * Previously, Moonflower and Primal Sunflower could also be used.
 * The player can only use sun-producing plants in the tutorial level of the Chinese version.
 * Sun Bombs can kill most plants, including Ghost Pepper.
