Top: In Super Mario 64, most Bob-ombs walk around in a small circle and charge Mario when they see him. If Mario approaches the center of the circle while the Bob-omb is facing away from him, then instead of turning around, the Bob-omb will continue walking in a straight line, leaving the circle.
Bottom: As long as Mario remains standing in the same spot, the Bob-omb will continue walking in the same direction indefinitely until it is eventually unloaded.
