Rotating defense mechanism

The rotating defense mechanism is a green obstacle that appears in the Secret Flower Field Entrance in the Wooded Kingdom in Super Mario Odyssey. It consists of four spinning circular panels with a Bowser symbol on each of them, which are required to be destroyed in order to enter the Secret Flower Field.

The rotating defense mechanism slowly and continuously spins counterclockwise until all four panels are destroyed. When Mario approaches it, it starts to launch rolling metal balls that also have Bowser symbols on them. The balls get launched from the hole in the center of this mechanism. The panels can be destroyed by shooting them after capturing a Sherm. After all four panels are destroyed, the mechanism stops and then breaks, revealing the Power Moon for the story mission Path to the Secret Flower Field and opening the gate to the Secret Flower Field.
