Note: None of these cameos are canon to Wii Funkin' or Matt's story.
For WiiK 2, however, the mic stays permanently in his left hand. In WiiK 1, he normally holds the mic in his right hand, but for all poses aside from his up pose, the mic shifts to his left hand.
For his WiiK2 he looks mad, abandons the sports equipment and his eyes have grey shading under them. These of course are all sports in the original game. Matt carries a basketball and various other items in his animations such as a basketball in his idle, a baseball bat in his down animation, a paddle in his right animation, a tennis racket in his left animation, and boxing gloves in his up animation.
