D Arrow: Crouch - D Arrow then Z: Spin Dash
Tails Nightmare Game
Oddly enough, Tail's Nightmare stars Tails as the main character. He is having one of those really bad dreams and the only way out is if someone wakes him up (not happening) or he finds his way out by using all of his patented moves like Spin Dashing and Flying.
