Everyone knows
What a Heffalump's like
It's got fiery eyes
And a tail with a spike
With claws on it's paws
That are sharp as a tack
And wing-a-ma-things
Coming out of it's back

Excuse me
What's a Heffalump?

Everyone knows
What a Heffalump's like
It's got fiery eyes
And a tail with a spike
With claws on it's paws
That are sharp as a tack
And wing-a-ma-things
Coming out of it's back
