This advertisement is known as "Bait" for obvious reasons.
A man is jogging by a lake and is attracted towards a new Toyota Vios which is parked next to the shore. As he approaches and touches it, it turns out to be a cardboard cut-out which falls to the ground. Just as it falls, a giant octopus like monster, appears out of the water and grabs the jogger pulling him under the water. The scene finishes with the monster using his tentacle to reposition the cardboard Toyota Vios cut-out to be ready for the next victim.
