IPL 9: Mumbai Indians' Harbhajan Singh's tricky question will leave you guessing!

New Delhi: Mumbai Indians Harbhajan Singh is quite active these days on social media. He has been tweeting and uploading pictures quite frequently.

But on Monday, the veteran off spinner uploaded his pictures with a huge monster-like truck and asked his fans to identify it.

It's actually difficult to guess the beast. Half-an-hour after tweeting, Bhajji gave more hints about the machine, by uploading yet another image of the huge car.

Guess if you can!
