Plants vs. Zombies: Revenge of the Target Zombies/Challenge Mode

Challenge Mode is similar to the Minigames concept in the original Plants vs. Zombies, Piñata Parties, and Brain Busters. Each level has something special about it in most cases.

Pea Party 1
The first challenge mode level. It's a day Lawn level. You have just one plant - Peashooter. Its cost is dropped to 25 sun, its recharge is increased to Very Fast, and sun drops from the sky 50% faster. There is one flag. The zombies are Zombie, Flag Zombie, Conehead Zombie, and Buckethead Zombie.

ZomBotany 1
The second challenge mode level. It's a day Lawn level. You get to choose any plant, and there are no changes to any aspect of normal levels besides the zombies. There are two flags. The zombies are Peashooter Zombie, which shoots low-power peas at your plants, and the Wall-nut Zombie, which has the health of a Buckethead Zombie, but it is not weak to the Magnet-shroom.

Wall-nut Bowling 1
The third challenge mode level. It's a day Lawn level. You bowl Wall-nuts and Explode-o-nuts at zombies; both come from the conveyor. Wall-nuts deal variable amounts of damage to zombies, depending on their armor, while Explode-o-nuts explode in a 3x3 area and deal half the damage a Cherry Bomb does, or the same as the standard instant kill. There is one flag. The zombies are Zombie, which takes one hit, Flag Zombie, which takes one hit but is ever so slightly quicker, Conehead Zombie, which takes 2 hits, Pole Vaulting Zombie, which vaults over the first Wall-nut or Explode-o-nut to pass it but otherwise takes one hit, and Buckethead Zombie, which takes 3 hits.

Solar Power 1
The fourth challenge mode level. It's a day Lawn level. You have one plant, the Sunflower, but unlike normal levels, these Sunflowers shoot rays of light. The rays start out weak, but the more Sunflowers you have, and the more sun you have collected, the more powerful they get. There are two flags. The zombies are Zombie, Flag Zombie, Conehead Zombie, Pole Vaulting Zombie, Buckethead Zombie, and Gargantuar. Gargantuar appears only during the final wave, and only at the very end of the wave, always in the center lane.

Good Morning 1
The fifth challenge mode level. It's a day lawn level. You are given the Sun-shroom, the Puff-shroom, the Fume-shroom, the Scaredy-shroom, the Tough-shroom, and the Coffee Bean. The Coffee Bean has a Very Fast recharge, and sun falls twice as fast until the end of the first flag, at which point it returns to normal. There are two flags. The zombies are Zombie, Flag Zombie, Conehead Zombie, Screen Door Zombie, and Dancing Zombie with its Backup Dancers.
