Sonic and his friends are standing in front of a large enthusiastic crowd of people as they raise their hands and say goodbye. Sonic is at the front, holding a sign that says "Bye," and wearing a confident smile as he basks in the joy and admiration of his friends. A rainbow of colors could be used to bring the scene to life, with Sonic and his friends wearing bright and vivid shades. Sonic himself can be given a vibrant blue hue to stand out from the crowd, and his sign can be painted a cheery yellow. The ground and sky can be filled with vibrant greens and blues, and the people in the crowd can be given a variety of colors to make the scene appear full of life and excitement.
