The levels in Super Mario 64 each have seven Power Stars and are laid out inside paintings inside the castle. In each level, one Power Star can be found by finding one hundred coins in the level, the other six are found by performing a variety of challenges within the level.
Levels often feature pink Bob-ombs called Bob-omb Buddies. They open cannons littered around the levels for Mario to fly with. When the cannon is open, Mario simply falls into the pit where it is, and it raises. The player targets the cannon with a cross hair shot, and fires allowing Mario to reach high or far away areas.
