There was one bellybutton,
Because the rest disappeared,
A floating bellybutton?
What Ben and I feared!!!
The bellybutton was scary,
And crazy, and spooky,
This whole night was turning,
Into something quite kooky!!!
The bellybutton floated,
Towards my house’s front door,

And I heard button shout,
504…
Ben and I laughed,
Ben and I screamed,
504 + 10 is _____
