Wire Trap

A Spiky Ring is an object found in the game Super Mario Sunshine, where they inhabit Bianco Hills and Noki Bay. They are either red or blue in colour and resemble spiral-shaped sea shells that are covered in spikes. Glowing sparks of electricity emit from their centers while they cling to a rope and move along it by spinning themselves. Normally, they appear on one side, travel to the other, then disappear, but they can do different. Depending on their color, their size and speed varies. Blue Spiked Rings are usually bigger and much slower than their red counterparts. Blue ones can constantly go from one side to the other and back without disappearing, and red ones may follow Mario. If Mario touches a Spiky Ring, he will get electrocuted and may fall off the rope. They are completely invincible, although the player can slightly hinder their progress by having FLUDD spraying water on them. The only way to avoid them is to jump over them.

Spiked Rings bear a slight resemblance to Lil' Sparkies and Hot Heads, as they too are enemies that move along a certain surface and damage Mario on contact.
