How to make it big

There's a lot that we can learn,
From the life of Mr. Kumbhakarn,
Who never did anything at once,
Any action took months and months.
Half the year for food, the rest for slumber,
His BMI would have been a rather high number!
The big 'little' brother of Mr. Ravan,
I can only guess the kinda life he was havin'
Grandma says he was kinda smart,
A huge body with a rather large heart.
He asked Lord Ravan to compromise,
"Leave Sita alone", he would advice,
This proves that Kumbha was very nice!
But what to do? He had a rakshasa bro,
Ravan was mad, waged war, and so,
Kumbha HAD to participate,
And he too caused destruction great!
For though he had much weight to lose,
He put his mass to quite good use,
He had a rather...peculiar niche,
Many a soldiers he could squish!
He ate like a hog, slept like a sloth,
His attire was made of miles of cloth,
Didn't work out, wasn't the sharpest knife,
Yet he turned out 'larger-than-life'!
