The Festival Dudes, if you don't remember, are the four enemies carrying around a portable shrine and can be found on the second and fourth floors of Inaba Pride Exhibit. Before heading out, there is a trick to this battle that will make it so the FOE doesn't use its one annoying skill, Diarahan. That is to construct a party of only four male characters, with Ken, Koromaru and Zen not counting, so you have a choice between P4 Protagonist, P3 Protagonist, Kanji, Akihiko, Shinjiro, Junpei and Yosuke. That's the only thing that happens if you do this, as it's entirely possible to beat the FOE without utilizing this trick.
The FOE only has a few moves in its repertoire, but the most damaging one is Crazed Slash, which hits random members between 5-7 times for good damage (150-200 or so). Other than that, it has Maragidyne, Gigantic Fist (splash damage to either side) and Megaton Slam (physical with medium chance of knockdown). If you're doing this battle the regular way, you want to get Magic Bind on it as soon as possible, so it doesn't heal itself completely (ignore Magic Bind if you're using the trick Elizabeth talked about). Strength Bind will also help, since all but one of its moves are physical based.
As far as weaknesses go, it is weak to ice and wind, but also resists bash, fire and all ailments/binds. With two weaknesses, it should be easy to get Boost on a good portion of your party members. For ailments, you might want to inflict poison on it, since 9800 HP is quite a lot and 710 HP loss every round while it's poisoned is quite good. You could also inflict panic on the FOE, as this will eliminate all of its attacks and also get rid of Diarahan, if you've chosen the normal route. Once you've taken the FOE out and gotten the required item, return to Elizabeth to finish the request.
