Tri-State Area is a world in Dark storm and its sequel. It won't appear in DS3, but it will be replaceed by an Avatar-themed world. It is based off the Phineas and Ferb cartoon.

Dark Storm
Stephen arrives on on this world after sealing Cul-de-sac. Dr. Doofenshmirtz sees Stephen with his telescope-inator, but decides not to let the hero bother him. Phineas and Ferb, meanwhile, meet Stephen and Candace tells them that she heard from Stacey that Stephen is the Hero of the Universe! Darkness then show up, however, and start to attack! After a battle, Stephen has proven himself to the boys. Agent P and Dr. Doofenshmirtz are fighting it up, and Stephen senses a large Darkness forming. After going to the Doffenshmirtz Evil building, and climbing ten floors, the Inator Darkness appears! Stephen then defeats it, and Candace leads him to the Panic Room to investigate something, and that something is the core! Stephen seals the core and leaves, obtaining Freezius and the Rollercoaster charm.

First Visit
Stephen revisits Tri-State Area after visiting Cul-de-sac for the first time. Here, Phineas and Ferb are trying to combine a Darkness and a soul. Stephen watches, but the power source was taken by a weird shadow! After fighting these shadows, Stephen finds Doofenshmirtz powering up a strange machine! Stephen defeats Dr. Doofensmirtz, but it's too late! The shadows mix with the machine, and the machine becomes the Evil Ray Darkness! After defeating the Evil Ray, the core is found in a pipe and selaed.

Second Visit(optional)
After Sunset Island is sealed, Stephen returns to Tri-State Area! There have been several strange power surges, followed by high winds, and topped off with a Darkness attack! Stephen decides to investigate, when several Darkness attack! Stephen runs to the outskirts of town, where the power generator is, and finds a Darkness scratching the machine, but still wants to find out the cause of the high winds! So Stephen scratches the grnerator during night, and the Air Battle Darkness appears! After a violent fight, Stephen is victorious, and Zapius Minimus is upgraded to Zapius Maximus.
