So, you finally reached Bottom of the Swamp Battle Cats. Honestly? My condolences. If you’ve been breezing through Uncanny Legends or even just wrapping up the later stages of Stories of Legend, this specific subchapter—officially known as "Palpitating Island" in the English release, though many players still call it by its Japanese-translated name—is where the game decides to stop playing nice. It’s swampy. It’s slow. It’s incredibly annoying.
The thing about these stages is that they aren't just about raw power. You can’t just throw a Level 50 Dasli at everything and hope for the best. Well, you can, but the stage design here is specifically built to punish players who don’t understand spacing and soul-crushing status effects. We’re talking about Toxic, we’re talking about high-pressure pushers, and we're talking about that one stage everyone hates: "Dreadful Drawbridge."
Let’s get into what’s actually happening in this swamp.
Why Everyone Struggles with Bottom of the Swamp
It's the design. Truly. Most of the enemies here are built to chip away at your frontline while the backliners—usually something with a massive area of effect—wipe your stack.
You’ve got to deal with Cadaver Bear. You’ve got to deal with H. Nah. If you aren't prepared for the sheer speed at which your money disappears because you're panic-summoning Meatshields, it’s game over in under two minutes. Most players fail here because they bring a "generalist" deck.
A generalist deck is a death sentence in the swamp.
You need specialists. You need units that can take a hit from a Winged Pigge and keep moving. You need units that can reset the frontline when the Zombies start burrowing behind your Uber Rare attackers. It’s a mess.
The Dreadful Drawbridge Problem
This is the peak of the subchapter's difficulty. If you’re stuck on "Dreadful Drawbridge," you aren't alone. It’s arguably one of the most polarizing stages in The Battle Cats. The stage features Zollow. Those little purple birds are the bane of my existence. They have a 100% chance to Toxic your cats, dealing 60% of their maximum HP as damage.

Two hits? Your cat is dead. It doesn't matter if it’s a Basic Cat or a massive Dragon Emperor.
The strategy here is counter-intuitive. You actually want fewer units on the field sometimes. If you flood the field with Meatshields, the Zollows just crash into them, trigger their area-of-effect Toxic explosion, and kill everything nearby. You have to time your spawns. It feels more like a rhythm game than a tower defense game at this point.
Honestly, the best way to handle this is using units with "Tough" or "Resistant" versus Zombies, but even then, Toxic ignores defense. You need units that can outrange them or units that are cheap enough to be expendable. Rock Cat (Stone Cat) is a godsend here. It takes the hit, dies anyway because that's its mechanic, but it stops the push.
Essential Units for Bottom of the Swamp Battle Cats
If you don't have these, go back and farm some Catfruit. Seriously.
- Cameraman Cat. With the Survive talent. It's non-negotiable. The sheer number of Floating and heavy-hitting enemies in these stages means you need a spammable attacker that stays on the field for more than one second.
- Cadaver Bear Cat. If you’ve unlocked this from the Outbreak stages, use it. It’s the ultimate counter to the very things that make this subchapter a nightmare.
- Pizza Cat. Specifically for the Black enemies that occasionally show up to ruin your day. With the Wave talent, Pizza Cat can clear the peons behind the bosses.
- Shigong Cat. The king of Zombie Meatshields. Without Shigong, the burrowing enemies will eat your base before you even see the boss.
Don’t sleep on the Rare cats. In Bottom of the Swamp Battle Cats, your Ubers are often just expensive targets. The Rares do the heavy lifting. I’ve seen people beat these stages with no Ubers at all, relying entirely on boosted Manic units and clever timing.
Dealing with the "Toxic" Meta
Toxic is a relatively "new" mechanic compared to the decade-long history of the game, and "Bottom of the Swamp" is where PONOS really started to flex how mean it could be.
Since Toxic does a percentage of your total health, your "Tank" cats like Ramen or Golem are suddenly useless. They have high HP, so the 60% damage from a Zollow hit is massive. Instead, focus on units with high attack speed or Long Distance (LD) capabilities. If you can kill the Zollows before they touch your frontline, you win. If they touch you? You're essentially playing a countdown clock until your frontline evaporates.

Strategy for "Swampy Sensation"
This stage is a marathon, not a sprint. You’re facing a mix of Bore and various support enemies. The trick here is controlling the Bore.
Use iCat if you have it. The Freeze effect is crucial. But be careful—the support enemies are there to knock your iCat back so the Bore can advance. You need a "layered" defense.
- Layer 1: Manic Eraser (Speed)
- Layer 2: Eraser Cat (Bulk)
- Layer 3: A mid-range attacker like Paris or Pizza.
If the Bore breaks through, it’s over. Use the Thunderbolt cannon to buy yourself those few precious seconds to respawn your freeze units.
The money tightens up mid-battle. Do not max out your Worker Cat level immediately. Keep it at level 3 or 4 until you’ve stabilized the frontline, or you’ll find yourself with no cash when the second Bore spawns. It's a common mistake. People get greedy with the wallet and then get steamrolled.
What Most Players Get Wrong About This Subchapter
They try to "power through" it.
You see it on the forums and Reddit all the time. "My Level 50 Gao is dying, is the game glitched?" No, the game isn't glitched; the stage is just designed to kill Gao.
The complexity of Bottom of the Swamp Battle Cats lies in the enemy synergy. A Winged Pigge slows your cats, and then a Zollow hits them with Toxic. It’s a combo. To break the combo, you have to prioritize the debuffers first. This usually means using units like Bullet Train Cat to snipe enemies or using a specialized Sniper the Cat power-up to keep the boss pushed back.

How to Prepare Your Loadout
Before you even enter the first stage, check your talents.
Have you invested in "Toxic Immunity"? There are a few units, like Hadal Vigler or certain specialized Gacha units, that can ignore Toxic. If you have them, the "Bottom of the Swamp" becomes a joke. If you don't? You're playing the game on Hard Mode.
Also, check your Cannon. While the standard Power Blast is fine, the Slow Beam or the Freeze Beam (Thunderbolt) is usually much more effective here. You aren't trying to do damage with the cannon; you're trying to manipulate the enemy's position.
Moving Past the Swamp
Once you clear this, the game changes again. You’ll start seeing more Colossus enemies and Behemoths. The lessons you learn in the swamp—specifically about not over-relying on high-HP tanks—will carry you through the rest of the late-game content.
The "Bottom of the Swamp" is basically a graduation ceremony. It’s the game asking: "Do you actually know how to play, or did you just get lucky with your Gacha pulls?"
If you're struggling, take a break. Farm some XP. Boost your specialized Rares to level 40 or 50. The difference between a level 30 Cameraman and a level 50 Cameraman is exactly what you need to survive a Zollow explosion.
Actionable Next Steps for Success:
- Upgrade your Research Combos: Use combos like "Cheating Heart" (Vigler + Madame Bride) to drastically decrease the recharge time of your Meatshields. In these stages, every millisecond counts.
- Farm Stone Cat: If you haven't cleared the "Sweet Child of Mine" advent stage to get Stone Cat, do it now. It is the single best counter to the high-damage pushers found in the swamp.
- Check Enemy Ranges: Use a database to look up the exact range of the enemies you are facing. If your attackers have a range of 350 and the boss has a range of 355, you are just throwing money away. Swap them for someone with 400+ range.
- Watch the Burrow: On Zombie stages, don't deploy your big hitters until the Zombies have already burrowed and resurfaced. Otherwise, they’ll just pop up behind your Megalodite and kill it in two bites.
- Master the "Wave" Timing: If you use units like Slapstick Cats, time their deployment so they reach the frontline exactly as the peon wave dies, ensuring they land their hits on the boss immediately.
The swamp is a grind, but it's beatable. Stop trying to brute force it and start playing the range game. Good luck, you're going to need it for the Drawbridge.
