3D Practice

3D Practice was a simple little prank uploaded to Newgrounds in 2008 by MysticSkillz. The animation, which was made with Adobe Flash, simply starts off by showing a series of 3D animations to catch the viewers' attention, but not long after that, a zombie pops up into the animation and shrieks. Surprisingly, this flash was rated suitable for everyone, though this was most likely done to trap certain users. The original maker or where the flash is after getting deleted from the site, are not known.
