"The 2012 Ace Race disc is now the Discraft Zombee, and it wants CHAAAAINS! Zombee isn't especially fast, but it is relentless in pursuit of its basket victims, moving in a straight line with added glide toward its prey. Zombee joins the Discraft hive as a utility driver with a 1.0 stability rating." — Discraft
