|"Of all the rotten luck!"|
|— Danny Phantom on bad luck|
In "13," Shadow causes bad luck for multiple people in a variety of ways.
Johnny sends Shadow to move a truck that Tucker is standing next to, causing it to crash into a roller coaster's structure.
While Tucker is explaining to others that he is not bad luck, Shadow pushes his hand up, making him accidentally toss his spoon into a bee hive, resulting in nearly the whole school being stung.
While Shadow is chasing after Danny, they phase through a popcorn machine at the movie theater, which causes it to malfunction right when Tucker is ordering snacks and once again insisting that he is not bad luck. The resulting flood of popcorn convinces Tucker otherwise, and he asks Sam to "goth him up" so he can get a new image to replace his reputation for bad luck.
