The Spikebar is an object in Sonic the Hedgehog, appearing in Spring Yard Zone. It is a chain of tiny spikeballs that swings around in a circular motion, hurting Sonic if he comes in contact with them.
This object was once a subtype of Object 57, and they still share the same circular movement code.
