Sonic-Con was a convention for fans of Sonic the Hedgehog, held at the local Sonic Fan Club HQ in the Great Forest. The convention's president was Sheldon, and the resident Sonic expert was Posey. In addition to the speaker's podium, the con had tables set up around the room where people sold memorabilia such as posters, T-shirts, and comics.
Sheldon initially invited Sonic himself to be the guest speaker at the convention, but when Sonic turned the offer down he invited Tails instead. However, Tails did not prepare a speech, and ended up making up a story about how he had fought the giant Toadzilla (in fact a small toad had surprised him on the way to the Con and made him fall in a stream). After the speech, Sonic-Con was attacked by Dr. Ivo Robotnik in a gigantic robot, but Tails managed to defeat Robotnik by making him dizzy and causing the robot to crash.
