The Knight Boat is a black speed boat that has been modified so that it's able to travel on both water and land. It sports extended exhaust pipes and wheels for land travel.
The Knight Boat is found only in Level 3. The player must get aboard the C-Spanker's top floor and find their way to several giant, green crates. They must jump onto the first two that are stacked, and then onto the three bigger crates. Inside the top one is the Knight Boat, facing reverse.
