UPDATE 4: THEMED PANDALS (HOW THEY LOOK LIKE)
Happy Dashami (Tenth & the last day of Durga Puja when the idols are immersed in holy water: rivers, ponds etc.)
This is an example of a themed puja pandal.
The attraction are the lights decorated & the idol made in a differentiating style due to which there is an immense crowd visiting those pandals.
Here they calculate the hits by feets stepped in their Pandal Area.
The investment is way higher than the Non-Theme Pujas.
But due to the attraction they get a huge crowd compared to the Non-Theme ones.
This type of pandals are the trend of Kolkata & are continuing every year.
