Elevator Alligators

You never know what could be hiding between the floors and walls!  Wouldn’t it be cool to live in this building?:

There’s a tall brick building
with flowers all around.
From outside it looks normal,
but strangeness there abounds!

The occupants have not a clue
though a girl who lives there knows,
that there’s Elevator Alligators
that play, while people doze.

Girl with alligator egg

The girl who found an alligator egg in her apartment building hallway.

They’ve been living there for many years.
No one knows the reason why.
They hide in walls, and in the pipes,
they really are quite sly.
