Quiz: Who is the Stowaway Passenger?

Our last trip to Terengganu was a very interesting one. One of the best part is the English program at SK Padang Hiliran. But there is another interesting incident… On the way to Terengganu (somewhere near the Gombak Toll), dad found somebody else on board! Can you guess WHO or WHAT is the unknown person or thing and WHERE is he/she hiding??? (Please send me your guesses via comment!)
