Song
A Xacoflaxian Singer is seen in Episode 4 singing a very patriotic song. He tells how he'll salute to the Xacoflaxian flag and pray to their god named Jibbody Libbody.

Lyrics:

I'm proud to be from planet Xacoflax. Home of freedom, land of liberty. And everyday I'll salute to the Xacoflaxian Flag. And pray to a god named Jibbody Libbody.

Xacoflaxian Flag
The Xacoflaxian Flag shows very close resemblance to the American flag.

It has 24 red dots over a green background in the top left corner. The rest of the flag is filled with purple/white diagonal stripes.
