Remix Files is a skit that aired as part of Donkey Kong Planet. As with many of the show's skits, it is framed as a trailer for an upcoming TV show. It is a parody of the long-running TV series The X-Files.
After a short montage consisting of the last 10 seconds of the X-Files opening, Agent Muldor and Agent Dana Loonie (corruptions of "Mulder" and "Dana Scully", the protagonists of X-Files) are shown investigating a park. Donkey Kong complains about the lack of UFO despite reports of there being one in the area, failing to notice the UFO right behind him. As he does so, a man is crushed by the duo's car due to Donkey Kong not properly using the hand brake. Due to the incident, Donkey and Candy are transferred to the "lamest department in the FBI", the Bureau des affaires bien anormales ("Bureau of Quite Unusual Occurences").
While Donkey and Candy are sleeping in the BABA office, a man dressed like a gnome enters and, introducing himself as OM, explains that zombies have invaded his front yard and that he cannot sleep. Candy dismisses the possibility as ludicrous, but the man explains that he investigated the matter and found that his house is built on an ancient Gallo-Roman cemetery. When the pair still proves to be uncooperative, OM threatens them by explaining he is distantly related to the president and that they should help him if they don't want to be transferred to "Plouc-sur-Yvette". They relent and agree to go on a "guided tour" of his front yard.
At OM's houses, the Kong zombies pop out of the ground and sing a song explaining that staying underground is annoying and boring, and that they like to party and play songs. Donkey Kong threatens to fine them for noise, but that he'll "look the other way" if they tone down the volume. The zombies sing the final section of their song and Donkey Kong congratulates himself on a job well done while OM is visibly fuming that the agents failed to resolve his problem.
