Cleansing Foam (BTD6)

"Sprays foam that removes Camo and Regrow and pops Lead Bloons."

- In-game description

Cleansing Foam is the 3rd upgrade of Path 2 for the Engineer Monkey in Bloons TD 6. It grants the Engineer Monkey with an independently shooting cleansing foam gun that regularly sprays cleansing foam around the Engineer's range every 2.0s (every 1.2s with 2-3-0). The foam blobs can remove the camo and regen properties from bloons that touch it, including from DDTs. They also damage Lead Bloons by cleansing them, converting normal Leads and Fortified Leads into Black Bloons, but zero damage to DDTs. Each foam blob can soak up to 10 bloons (15 with 0-3-1 or 0-3-2) or 8.5s before disappearing, whichever comes first.

Starting from Version 29.0, Cleansing Foam's foam will default on Close and can be retargeted to any valid location within the Engineer's immediate range, including on non-track locations.

It costs $680 on Easy, $800 on Medium, $865 on Hard, and $960 on Impoppable.

Summary
Cleansing Foam fulfills a similar role to its BTD5 counterpart, removing Camo and Regrow properties off bloons hit by the foam globs. The difference, however, is that Cleansing Foam now comes with large range already and targets consistently on a given location. It is not necessary to the Engineer away from the track, as the Foam can be smartly targeted to any desired location within range. Path 1 crosspath not only provides the Engineer with needed extra sources of popping power, it also enhances the production speed of foam globs by a significant amount with Faster Engineering, at a +66% increase, compared to Path 3 with just gives pierce.

Tips

 * Use 2-3-0 Cleansing Foam for the added DPS from the Sentries plus much faster reload of the foam attacks. In fact, the attack speed of foam increases by +66% compared to just +50% (or around 38% with Thicker Foams) pierce from the opposite 0-3-1 (or 0-3-2) crosspath.
 * Remember that the foam attacks from Cleansing Foam can ignore Line of Sight, so it might be worth considering this in specific situations.
 * With the Monkey Knowledge "Thicker Foams", the cleansing foam's pierce increases by 3.
 * Cleansing Foam will take the camo off DDTs, making this one of the cheapest ways to allow towers to attack DDTs.
 * Cleansing Foam does not damage DDTs, despite dealing damage to normal Leads. This can be useful for All Pops CHIMPS challenges when using Overclock.
 * One can target Foam away from the track to intentionally decamo DDTs and not waste so much pierce on regular bloons.

Sounds
When deploying Cleansing Foam:


 * [foam bubbling]
 * [foam bubbling]
 * [foam bubbling]
 * [foam bubbling]

Trivia

 * In BTD6, there is a specific glob-dispensing sound for Cleansing Foam placement. In BTD5 generation games, there was no specific sound for them. Additionally, foam globs are dispensed near-immediately onto the track upon spawning from the Engineer, rather than projectile-based like Spike Factory spikes as the foam globs were in BTD5.
