Bite Club is a Halloween episode of I Didn't Do It.
The episode starts off at Rumble Juice and Garrett is seen working. Logan and Delia tell him that they are going to New York for a science presentation, to present what they once did for science homework. (Lindy in the Middle), and head to New York. Betty asks Garrett to take her nephew, Kevin, trick-or-treating on Halloween night because she'd be working and he eventually gives in. Jasmine and Lindy, on the night before Halloween, go to Rumble Juice and run into a strange man. He asks them to give blood, which Lindy happily accepts to do, but Jasmine decides not too after she notices that the guy is wearing fangs, which starts to creep her out. Jasmine tries to convince Lindy that the guy really is a vampire, but she doesn't believe her.
In New York, after Delia and Logan have done their presentation, they go to Central Park, where they run into Trish and Dez (Austin & Ally). The four quickly get a long and Trish and Dez convince Logan and Delia to go see a fortune teller, which they do. Meanwhile, back at Rumble Juice, Garrett comes in dressed up as Roy Boy, to collect Kevin to take him trick or treating. Kevin at first isn't so sure on this, because he thinks of Garrett as a loser, but goes anyway.
A few hours later, in Rumble Juice, Jasmine notices that Lindy doesn't look so good and asks her if she's okay. Jasmine finds bite marks on Lindy's neck is now fully convinced that Lindy will soon turn into a vampire, especially after Lindy says she likes a smoothie that possibly has blood in it, creeping Jasmine out.
Back in New York, Logan and Delia go to the fortune teller, who convinces Logan that if he waits in a bush all night, good things will happen, but they don't. Meanwhile, Garrett and Kevin try to trick a lady they have already had candy from, by dressing up as different people. The lady buys their game and gives them lots of candy. Jasmine walks into the basement and sees Lindy lying down on the couch looking really pale. Lindy pulls a prank on Jasmine, trying to convince her that she is a vampire, when Lindy pretends to try to kill Jasmine by biting her, which terrifies Jasmine and Lindy tells Jasmine that she was just pranking her.
In the final scene, at Rumble Juice, everyone is hanging out, looking at each other's pictures from Halloween night. Jasmine notices the supposed vampire guy isn't in one of the pictures, but Lindy shows him in another picture. Delia shows everyone the pictures she took of her and Logan in New York. Delia mentions that she and Logan met Trish and Dez, and Logan says that Dez is their Logan, ending the episode.
