In Super Mario Galaxy, Mario’s flattened body can be made to fly around the level after dying through a glitch. In the Fast Foes of Toy Time comet mission in Toy Time Galaxy, positioning Mario inside a Tox Box when it is turning can sometimes result in him being squished and losing a life; however, instead of his body remaining in place, it flies up in the air. The camera attempts to follow the body and finally focuses on it when it lands on the ground; then it flies away again as the loss/Game Over animation plays.
