Special: Melons damage nearby enemies on impact
Firing Speed: 1/2
Unlocked: After beating Level 5-8
Planted On: Ground, Lily Pad, Flower Pot
Upgraded To: Winter Melon
Melon-Pults shot watermelons at zombies, doing splash damage to other nearby zombies. Each melon does 4 peas worth of damage, making them equal to two Cabbage-Pults, or 2 Repeaters, or 4 Peashooters.
Melon-pults can hit Newspaper Zombies, Screen Door Zombies, and Ladder Zombies over their shields, and Snorkel Zombies while they’re underwater.
Comparing two Melon-pults to a Gatling Pea and a Torchwood: A Melon-pult does only four peas of damage per second. Considering its splash damage, which is two peas per second in ideal conditions, its average damage per second per row would be, given a zombie density of one per square, 7. With a lower zombie density, this is much lower. A Gatling Pea and a Torchwood would do eight peas of damage per second, given a zombie density of 1 per square (and an extra four peas for each zombie on that square) while taking up the same space on the field. Also, the Gatling Pea and Torchwood combination (with the Repeater) takes up three slots in the seed tray. Given one zombie, Three Melons To Die the two Melon-pults will do a meager four peas per second, and the Gatling Pea and Torchwood still does 8 peas per second.
Thus, the tradeoff would be two extra slots in the seed tray for around four peas of damage per second per row (given one zombie) and 25 sun. Note that as more Gatling Peas are added, the damage gap increases and the sun gap decreases (and goes negative). For example, with two Gatling Peas and a Torchwood versus three Melon-pults, the former does 16 peas of damage, and the latter does 12 peas per second. However, as the zombie density increase, the Melon-pults quickly do much more damage per second, while the damage per second of the Gatling Peas increases much less. Also, as a Wall-nut, Tall-nut, or Pumpkin comes into play, the Gatling Peas become less effective, relatively speaking, as the zombies pile up on the same square. Also, due to the roof’s angle, the Gatling Pea strategy is useless on the roof unless it is planted on the right side but would be considered highly dangerous.
