Spike Bar

Spike Bars are hazardous obstacles that are shown to first appear in Super Mario 3D Land. In the game, they are essentially duplicates of Fire Bars except without any burning properties. However, unlike Fire Bars (which mostly only appear in lava-themed levels), Spike Bars are found all over the place including levels like World 2-4 and World 5-3. Like Fire Bars, there can be two Spike Bars rotating at the same axis. But unlike Fire Bars, there has never been a Spike Bar to rotate on its side nor has a Spike Bar with more than two bars rotating at the same axis been spotted.

Spike Bars return in Super Mario 3D World, however their appearance has changed. This time they look more like spiked rollers rolling around a center than Fire Bars. They also are only seen with two or four bars rotating at the same axis. Spike Bars are only found in and. Additionally, Spikes attack by producing unattached Spike Bars and throwing them, which roll down the path in front of them. Other individual Spike Bars can also be found rolling on pendulum platforms, or swinging back and forth via two chains.

Spike Bars reappear in Captain Toad: Treasure Tracker.
