Volcano, taco, cradle... DWARF DOOR. Nerang Skatepark in Queensland is the one whose Skateboarding.com.au page proudly proclaims "Dwarf door! Yeah the only park in the country with a dwarf door which makes it a must stop. The door is in an open bowl section that also has an extension and small taco" (although Charlton skatepark in VIC also has a tiny one: a pixie door I guess).
