Kaboomerang

Kaboomerang is an upgrade plant of the Bloomerang in Plants vs. Zombies: The Final Showdown, throwing explosive boomerangs for extra crowd control.

The Kaboomerang's shots deal twice as much damage as a normal Bloomerang's shots (40 DPS instead of 20) and explode after their third hit, dealing an extra 20 DPS on that space.

An unusual quirk of this is that it has higher DPS against single targets when there are less zombies around. A lone zombie will get hit by the double damage boomerang twice, essentially meaning it will take twice as much damage as if it were hit by a Bloomerang. However, if two zombies are in the row, it will hit the second one twice and the first one once, then deal explosion damage to one or both, depending on how close they are to each other. With three or more zombies, each one only gets hit once before it explodes.

It is unlocked by purchasing it from Burt's Bits & Bobs for $3,000.

Cost: 125

Recharge: very slow

Plant Food
Two boomerangs orbit around it for the next thirty seconds, causing 1x1 explosions whenever they hit a zombie, and each makes two full orbits per second, for four explosions. Each explosion deals 100 DPS, causing it to deal around 20 peas of damage in a second.

Strategies
The Kaboomerang should be used similarly to Bloomerangs, however there are a few ways to maximise its efficiency. Pairing it up with other effective AoE plants like Laser Beans, Fume-shrooms, or Melon-pults will thin out crowds faster and allow it to deal maximum DPS to stronger targets such as Bucketheads, or you could use Garlic, Winter Melons, or defensive plants to group up zombies more densely so more are hit by the explosions.

Keep in mind that its DPS isn't very high due to it still possessing the slow attack speed of a Bloomerang. However, the AoE damage provided is still very effective against zombies and setting these up is a good investment in medium length levels.
