Kuber, the God of wealth wanted to show- off his wealth and puffed up with ego he invited everyone. Shivji sent Ganapati ji to the Party. 

Ganeshji - Ganapatiji went to the party and he wanted to eat all the yummy food. When he became unstoppable, and started eating everything, all got scared and started praying and chanting.

- Shuklambara dharm Vishnu (Shloka)

Still he did not stop so the called out loudly for the greatest devotee of Ganeshji - Bappa Moriya.

Mantra

- Ganapati bappa moriya, mangal murti morya

- Moriya re bappa moriya re

But, Bappa moriya did not come to help them and calm Ganapatiji down, as he knew that Ganeshji was teaching Kuber a lesson.

Finally, God Kuber rushed to Kailash and got a hand full of puffed rice filled with parvatiji’s love. This made Ganeshji full and they all sang for him and he fell a sleep.

Bappa Moriya came and cuddled little Ganeshji and dropped him home to Shivji, Ma Parvathiji and brother Kartikeya

So, the morals are,

- When god is kind to us and gives us wealth, we should not use it to show off, but to give and share with everyone

- The greatest wealth is love. The heart filled with love is the richest heart in the world.

- If we don’t learn to be good ourselves, god has many ways of teaching us a lesson.
