Sonic Adventure: Tremble Park

Tremble Park is event data that could be downloaded to the player's VMU for use in Sonic Adventure, commemorating Halloween. Posters reading "Happy Halloween" are plastered all over Station Square, with a large mat on the ground in front of Twinkle Park's entrance with the same design. Stepping on it tells the player a Halloween party is being held there. Twinkle Park has large "trick or treat" graffiti messages spray-painted all over the place, and ghosts float around, which also say "Trick or Treat!" when touched. While generally harmless, ghosts on the bowling lanes will stop the player if they run into them.
