MTG Creeping Tar Pit?

[OldManFan]

If my Creeping Tar Pit takes creature form during my attack phase, what happens when he gets hit by a lightning Bolt?

 

[devius]

he takes 3 damage which is lethal and go into the graveyard.

 

[SamLaufer]

He'll go to your graveyard since his toughness is less than 3.
