"The Fairly Odd Phantom" is a short that is a crossover of all of Butch Hartman's shows: Danny Phantom, T.U.F.F. Puppy, The Fairly OddParents!, and Bunsen Is a Beast. It serves as a promotional short for Bunsen is a Beast.
The short opens on Danny, Sam, Tucker, and Jazz in the lab. Danny says that the Ghost Portal has been acting weird lately, and then the alarm goes off and three ghosts pop out of the portal. Danny transforms, and Sam, Jazz, and Tucker help him take care of them.
The foursome wonder what could be the cause of the Ghost Portal's strange behavior. Then they see that Dudley Puppy is messing with the Ghost Portal controls, with Kitty Katswell looking on in displeasure. The alarm goes off again, and this time, Timmy Turner, Cosmo, and Wanda step out of the portal. Timmy remarks that the lab isn't Fairy World, and Danny mistakes Cosmo and Wanda for ghosts and sucks them into the Fenton Thermos.
The alarm goes off one more time, and Bunsen steps out. Bunsen thinks the group is there for a party and gives everyone cupcakes. Dudley eats them all, except Timmy's, and Danny makes a new rule: "Only people with pants are allowed in the lab." The short then ends.
- It is unknown if this short is canon. However, if it is, it means that Danny Phantom, T.U.F.F Puppy, The Fairly OddParents!, and Bunsen is a Beast exist in the same universe.
- Due to Jimmy Timmy Power Hour, this could also mean that Jimmy Neutron exists in this universe as well.
- This marks the first new Danny Phantom animation in almost ten years.
- This is the only Danny Phantom short and its only "crossover" episode so far.
- While Danny is in ghost form, he is missing his typical tan skin, white aura, and ghostly voice.
- As this is constant throughout the video, it is uncertain if this is intentional or merely an animation error.
