The Thorn Spring is a reoccurring gimmick that appears in the Sonic the Hedgehog series. It is a hazardous variant of the Spring which has spikes equipped on the bottom.


The Thorn Spring is a floating object with a standard modern Spring on top and a metallic cup on the bottom which surface is covered in spikes. In gameplay, the Thorn Spring flips itself upside down for a short while in fixed intervals, making either its Spring or spikes point upward. The player can either touch them normally or target them with a Homing Attack.

When touching the Thorn Spike while the Spring-side is up, it works like a regular Spring, launching the player through midair to another location. If the spike-side is up though, the player will take damage upon touching it. Using this gimmick properly is thus based on timing.
