It’s not even a duck! - ―Dispatcher dialogue on Wave 10 (Bathroom Approach)
Description
P3NGU was an enemy that appeared in Bathroom Approach as part of the Ducky Revenge Event and its rerun in the Spring Frenzy Battle Pass. It has a high amount of health and 30% Defense, but it walks rather slowly.
P3NGU has one ability, Beak Beam, where it will attack a tower with a laser fired from its beak. This laser will attack the targeted tower, stunning it and any other nearby tower in its attack cone for 4 seconds while also dealing 20 damage to units per tick. This ability has a tick of 0.1 and a range of 15.
Logbook Description
"P3NGU is the latest addition to Nerd Duck's inventions. Powered by cutting-edge bird technology, Nerd Duck based it on a flightless bird concept; something that's completely impossible. After all, a creature that waddles and can't fly couldn't possibly exist, right?"
Appearance
P3NGU is a regular penguin turned into a mech, with the only parts of its body not being entirely covered with mechanical parts being its torso and wings. On its mechanical head, it had giant, neon red eyes, and on its torso, it has a neon red light. All of its mechanical parts are connected to its body with giant screws. P3NGU also has a large metal jetpack on its back.
Event Strategy
As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in Bathroom Approach is listed instead.
- High DPS towers like the Pursuit, Crook Boss, Golden Minigunner, Ranger or Turret can be used to kill P3NGU.
- Defense reducing towers like the Pyromancer, Electroshocker or Freezer can be used to reduce its defense.
- Do note that, on certain waves, P3NGU is a Freeze Immune enemy. This means freezing towers will be unable to reduce its defense.
- As for most waves, P3NGU does not have any stalling immunities, some of these towers can be used to also stall them.

Trivia
- A "Noot noot!" sound can be heard once the P3NGU stops firing, which is a reference to Pingu.
