Aliens from the Planet Fred

I'm friends with aliens,
All from the planet Fred,
I've seen other aliens before,
But they were all lying dead!

They are very strange,
These alien friends have eight arms,
So they're really helpful carrying,
And they don't intend to harm!

These alien friends have four legs,
So they have to walk funny,
And they climb trees easily,
While they are hunting for honey!

These alien friends have six eyes,
Two for each head they've got,
But they're terribly nearsighted,
So humans are not easy to spot.

These alien friends have three heads,
One's hungry, serious, and one's very funny,
Yet they often get into fights,
Calling each other "dummy."

Their ship's engine is purple,
But I'm told it's supposed to be blue,
That's what they stopped here for,
They don't know what to do!

Their air conditioner is green,
But I've seen it turn yellow,
I'm told it changes settings by itself,
You can tell by when it bellows!

When it is landded it's orange,
And when it takes off it turns black,
My two favorite colors,
I like it like that!

I'm friend with aliens,
All from the planet Fred,
I've seen other aliens before,
But they were all lying dead!
