Meteor

Meteor Spark Event, which is now also Lightning Spark Event has 6 powerups (Power, Mine, Jump, Spark, Dash, Ghost) that spawn on the track at random during the race, only 1 powerup per race can spawn. This is my favorite mode, I like it more than the standard races because I enjoy the chaos and having to adapt to hazards in real time.

Master A1 created a Meteor guide for how all the powerups work, very informative and goes in-depth about every aspect of this mode.
