The Veloci-Rooster is a chicken that wanders around the street in The Sims Bustin' Out for GBA. The Veloci-Rooster runs around very fast, and if it catches up on the Sim, the Sim may get knocked out by it, so the players have to be cautious with it. The players may be aware of its presence as it makes a rooster sound.
In the game, Daddy Bigbucks gives the players a mission to capture the Veloci-Rooster. The players require at least 6 Body skill points in order to catch it. Once the mission is completed, the Veloci-Rooster will no longer appear to disturb Sims.
- The Veloci Rooster might be a reference or a pun to the Velociraptor, a small and agile dinosaur species.
- Veloci-Rooster is said to be responsible for Nora Zeal-Ott's mother's death.
- In The Urbz: Sims in the City (handheld), during mission 3-3 when guarding the graveyard, the players will tell Daddy Bigbucks, "Think again I'm as free as a Veloci-Rooster," which is rather ironic because in The Sims Bustin' Out for handheld, the players have to catch the Veloci-Rooster.
