Where Did All The Lizards Come From?

For a city, Without a clear water source, It's probably not surprising, But the lizards here are thriving, Scale-ey reptiles, That walk and talk, "Is that a giant alligator?", "I like his look, "HE ROCKS!!" They got shiny scales, look so pretty, Shimmering diamonds in this super-city, Long tongues that utter eloquent sentences, Maybe they do other things too, We can't mention in a song, "'Cause it's wrong!" Swooping above the clouds, Wings touching the tops of skyscrapers, Majestic dragons soar like they are made of paper, They glitter, "oooooohhhhh I like glitter", In the sun, But where the "HECK" did all these lizards, Come from? Was it a portal, To a lizard world we opened? With all the tinkering around in the lab, They might've upset the balance, Or the lizards somehow thought we were important. I've seen Alligators, Iguanas, Komodos and Monitors, And did I say I've seen a frickin', fraggin', "REAL HUGE ", "ACTUAL DRAGON!" They got shiny scales, look so pretty, Shimmering diamonds in this super-city, Long tongues that utter eloquent sen-ten-ces, Maybe they do other things too, We can't mention in a song, "'Cause it's wrong!" Swooping above the clouds, Wings touching the tops of skyscrapers, Majestic dragons soar like they are made of paper, They glitter "oooooohhhhh I like glitter", In the sun, But where the heck did all these lizards, Come from?
