The Big One

The Big One is an enemy in Swamp Attack.

It is the boss of Episode 6.

Abilities
The Big One will utilize high-damage chemical fumes to damage your house. There is no way to defend against this attack. Additionally, it can only be damaged by shooting at it's open eyes. Since the eyes will close after some time, do not attack until another opens, as it otherwise does nothing to the enemy. It is only defeated when all the eyes are destroyed.

The Big One can be also frozen with the Fridge, as while this will disable the fume attack, the eyes will still play their animations normally, so they can be damaged.

Trivia

 * Multiple enemies in great resemblance to it appears in the cut-scene after finishing episode 5, where a Bee attempts to land on one of them but is terrified by the eyes and proceeds to depart.
 * It is the second boss with multiple units on it's body that the player needs to attack in order to defeat it.
 * However, unlike the Alien Mothership, The Big One's eyes all share the health of the boss itself.
 * The eyes are only destroyed when the boss loses a certain quantity of health, instead of being defeated separately, like the turret guns of the mothership.
 * It appears to resemble a lump of green moss mutated by radioactive waste.
