After the Savoy incident, Tony is given a prosthetic ear, and is placed with his former partner John Colby. Applebee sends the two to investigate a bank robbery where the only evidence left behind was a pile of feces. With Tony refusing to eat it, John suggests that they attempt to solve the crime by doing actual detective work. They found the perpetrators with the money, and illegal chicken. Tasting the chicken soup, Tony soon realizes that it's not chicken, but an odd fruit named gallsaberry.
Trying to find the location of the strange chicken fruit, Tony goes with Chow to the island of Yamapalu. He is soon confronted by USDA agent Lin Sae Woo. He states that he was only tracking the fruit, and not trying to horn in on her case. She tells Tony that they'll meet at a bar and exchange information. So Tony waits, only for Lin to not show up. Tony is soon after arrested for the murder of Lin Sae Woo. While in jail, Tony is beat up by two men, and is saved by officer Raymond Kulolo after he is confirmed to be a member of the FDA. Tony goes to investigate a murder with Kulolo that he flashed on when he bit an inmate. They discover the body and learn that the man was killed over a championship cockfighting rooster. The two then find the rooster, named Poyo, and take it to the police station. Kulolo allows Chu to take a look at Lin's body. After leaving the room Tony realizes that Kulolo cheated him and made off with the rooster, he also left him one of the chicken fruits he was after. After taking a bite, Tony realizes that the fruit is out of this world.
After taking a bite from one of the bodies at the island morgue, Tony learns that a vampire is storming the island, and is going to try to steal one of the governor's chefs. He also sees that the vampire killed Lin. Tony sneaks into the governor's compound and rescues both Chow and Amelia. He tells them to go south, but then stops when he sees that a gigantic fire is growing in that direction. Tony goes back for the chef Fatanyeros, and finds the vampire with him and the governor. The governor attacks Chu, and takes his gun. The vampire leaves with Fatanyeros and tells Tony that they'll meet again. Tony helplessly watches as the governor killed himself. Tony then leaves the island with Chow and Amelia. Upon his return, Director Applebee is strangely treating Tony nicely, and Tony gets the nerve to call Amelia. He gets nervous and doesn't say anything, but Amelia knew why he called, and she sets up a date.
