Terror Tennis is a minigame found in Mario Power Tennis. Players attempt to score points by hitting ghosts (from Luigi's Mansion) back in their portraits. There are Gold Ghosts, Purple Punchers, Blue Twirlers and Garbage Can Ghosts. A player will earn more points if a ghost is hit rather than just its picture. A Bowling Ghost will throw the player a new ball if the current one was missed or improperly hit.
This is played on the Luigi's Mansion Court.
