Flamingo and the Zoo Keeper; the rest of the story

Nadia and Luka looked so cute when I took them to the zoo today.  Luka made no fuss about the outfit I chose for him while Nadia took a whole two days to persuade to dress like a pink flamingo instead of a peacock.  I went on and on about how pretty the flamingos were and how she can stand on one leg just like they do.  I argued that it's really only the boy peacocks that look pretty and would she really want to dress like a boy?  In the end she agreed happily that the flamingo was the way to go and she couldn't wait to compare herself to the real thing.
So....this morning I woke up the kids and surprised them with super delicious homemade monkey bread (100% sugar and carbs, and I one-and-a-halved the caramel sauce to make them extra gooey) and we dressed and headed to the zoo on our sugar high.  After about an hour at the zoo the crash (and burn) set in and Luka had had enough.  He pooped then started screaming at the top of his lungs and and threw his juice bottle on the ground repeatedly after kind strangers kept giving it back to him.  I changed his pants and even though this only quieted him for a mili-second, I had promised Nadia a carousel ride. After the ride, I tried to sneak out of the zoo without having to go all the way to the other end to see the ever beautiful pink flamingos I had spend two days talking about.  We got all the way to the gates, Luka strapped in the wagon wailing as if he had been severely beaten and trying his best to throw himself over the sides even though he was strapped in, when Nadia looked around and asked with huge tears welling in her eyes, "where's the pink-amingos?  I want to see the pink-amingos!"  I tried to explain that they were sleeping, that it was too hot for them and that they must have been hiding today but she would have none of it.  She remembered where they lived from our previous zoo exhibitions and called me out right in front of the one of the zoo guards. 
There was no way she was going to walk fast enough to get this over with at the rate it needed to be over. I threw her in the wagon and at least she looked cute with her triumphant smile as I hauled her, the cooler and the hysterical, screaming, flailing mass that was Luka all the way back across the zoo.  Did I mention that the cooler was much too big for the wagon so Nadia had to stand in front of Luka where she hunched over the top of the cooler trying not to get kicked? Children stopped and stared at us.  Parents looked away.  Some of the smaller animals ran and hid. 
We made it to the flamingos.  I took a few pictures of Nadia while Luka caught his breath.  After Luka had fully resumed kicking and screaming we headed back to the car.  After about a minute I looked back and Luka wasn't wearing his hat.  I would have kept going and just said screw the hat, but we had come this far, what was one more round back to the flamingos?  Everyone had already seen the sight, it's not like I was seconds from peace and quiet, right?  So we went back, got the hat and I stuffed it in my purse.  A quick look to see that there was nothing that could be thrown, dropped or forgotten and I bolted for the car.
I walked as fast as I could, looking straight ahead not making eye contact with anyone.  I didn't look back at the kids but just listened for Luka's screams and Nadia's "Ouch! Luka kicked me!"'s to know that no one had fallen out of the wagon or gotten a stray arm or leg run over by the wheels.
We made it back to the car in 30 minutes, it may have been the longest thirty minutes on record.  Luka slept the whole way home.
