Late last month Nintendo UK showed off 3 Mario Kart 8 tracks via their Twitter account.  Now they are at it again and this time give us a small peek at 4 more tracks for Mario Kart 8.  Previously they showed us pictures of Mario Circuit, Thwomp Ruins, and Sweet Sweet Canyon.  This time around we get a look at Toad Harbour, Twisted Mansion, Cloudtop Cruise, and Bone Dry Dunes.  The pictures of the tracks can be viewed below.  Mario Kart 8 releases on Wii U May 29th in Japan, May 30th in North America and Europe, and May 31st in Australia.
