The trap left by the Star Trail takes the form of a yellow five-pointed star. This particular object glows yellow and emits bright sparkles.
In gameplay, Star Trails can only be obtained at random from Item Boxes by Zazz. As with all most Items, Metal Sonic can also use the Star Trails if he uses the Steal Item to steal it from the aforementioned user.
When using this power-up, the user drops a number of stars behind them as they move forward. These stars will then set themselves permanently on the spot on the lane they were dropped on for the duration of the race. Should an opposing racer make contact with one of the Star Trail traps, they will not only take damage, but also have a portion of their Rings transferred over to the user's Ring count.
The Star Trail is based on the star-shaped projectiles that are deployed by Zazz's Moon Mech.
