Halloween time can be the stuff of 'Nightmares'. Brazil's Plastic Robots is back on Dirtybird with Underlow for a dark and driving track fitting for the holiday. Keeping with the shadowy theme is 'Armada', a rolling beater with an intense and nasty build.

For a bonus, head over to the Birdfeed for an exclusive remix of 'Nightmares' from Fab Massimo.
