The sinks have been successfully clogged with whatever paper the penguins could salvage from Kowalski's idea clipboard, and the toilets were most certainly clogged with toilet paper. The taco couldn't climb in the sewer now. And as for the door, it was successfully barricaded with bodies for all the penguins minus Rico were piled in front of the door, holding back the pressure put upon it by the great taco terror.
Skipper: Hang on, prairie dogs!
Private(whining): We should have gone to IHop!
Kowalski: What are we going to do? We are trapped in a bathroom and to make it even worse there is a mutant taco breaching our ranks AND to make it worse worse this bathroom is stinking of clogged toilets. We will rot in here like a dead body rotting in the heat and decaying-
Skipper: We don't need grusome details. We need a plan. Kowalski, options. Private, fill me in on every detail. I can take it.
After much thought they have a plan. Master genius Kowalski decided that...No time to finish telling you the plan. The taco just burst in through the door! There is no resistance holding it back and it searches with eyes made of olives for the three remaining penguins. But they aren't there.
Skipper: Now, now, now!
With perfect military fashion the penguins drop fom the ceiling and out the open door. Skipper dives under a table to safety.
Skipper: The plan worked! High fives, men!
Kowalski: Now is not the time for jollity. Where is Private?
Private: AHHHHHH!!!!!
They look out and see Private being swallowed up in the giant taco, disappearing behing two soggy hardshells. For a moment they stay silent to honor the soldier who was devoured right before their eyes.
Kowalski: I can't believe it. Eaten. Gone, just like Rico! Oh the irony!
Skipper: We are getting out of here. That hardshell horror is not going to win this battle.
Kowalski: But it will eat us! Waht do we do? To create an assault, the odds against us would be extremely high...
Skipper: Keep it together, man. We are getting out of here. I have a new plan.
Kowalski: Elaborate.
Skipper: Yep, we are going to spit in the face of danger. Wait for it....We are going to face the monster head-on! That's right. You heard me. Now here's the plan...
(The camera is slowly moving out from beneath the gum encrusted table so we can't hear the plan. I know how much we all want to know how they get out of this epidemic, but that will have to wait. In action movies they always zoom out when the plan is being said! That ruins the suspense for later!)
