A Magical Kingdom A Magical Kingdom is a quest in the " Fallout 4 " add - on " Nuka - World " . Detailed walkthrough . When first entering Kiddie Kingdom from the south , a voice will greet the Sole Survivor and goad them to look for the owner in the tunnels , the theater and the Fun House , as well as inform them that the park is constantly covered by a thick cloud of radioactive gas by sprayers installed all across the park . Tunnels . The entrance to the employee tunnels is located to the east of the Ferris wheel . Moving onwards , the halls lead down into a bunker , where a terminal mentions how the park employees sheltered down in the tunnels and slowly changed into feral ghouls from radiation exposure . Through a hole in the rear wall , the voice — belonging to a glowing one named Oswald — speaks to a feral as if it were sentient . He states that the visitor ( in reference to the player character ) is unlike any other he ' s met and wants to prepare for them . Then , in true magician form , he disappears in a puff of smoke . Move around to the left , staying near the wall and hop onto the stairs , avoiding the glowing pool of water , as it will cause 10 - 20 rads / second of damage . Enter the booth and use the terminal to shut off the sprayers . Retrace the Sole Survivor ' s steps to the window and exit the tunnels . Fun house . Exiting the door will lead the to a coaster track , where two cars will zip down the tracks at different intervals . Being struck by them will cause considerable damage . Run down the tracks and emerge in a courtyard full of ghouls . Oswald has reactivated the sprayers , meaning the radiation will still be strong in the park . The tunnel luckily exits near the Fun House . Enter the facility and proceed into the Hall of Mirrors . While not as confusing as a normal fun house , due to centuries of dirt and grime , the room is still dangerous . Proceed carefully , as two enemies are hiding behind the cloudy reflections . One is a feral ghoul , crouched with its back turned away . The other is a radroach , which will pounce once the ammo box beneath it is approached , though a frag mine ahead may kill it first . At the end of the hall , the doors lead to another long hall . Past the first security gate , Oswald will start up a conveyor belt floor , easily outpaced by running , though at certain points grenades will drop from the ceiling . Run , with the occasional jump , to reach the end . The next room has two spinning platforms to scale over . The next room is the Hypno Hall . A terminal to the left of the door allows for a less nausea - inducing experience . Take the swirling hall on the right , then go left and straight to find SCAV ! issue # 3 next to a dead raider . Retrace and go through the hall to the right . Ignore the several swirling images , as well as possible , and fight off two painted ghouls near the end . Through the door , a charred ghoul greets one ' s arrival . Going through the topsy - turvy room leads to a room of many doors , a spinning floor and more ghouls . After the fight , search the many doors . When the player character has had their fill of free loot — and several pop - culture references — going through the correct door will lead them to the chained door back to the exit and the hall up to the control room . Here , Oswald has already fled , but promises to keep the fun up . Deactivate the security gates , in addition to grabbing the Nuka - Lixir recipe next to the terminal , then exit the Fun House . Theater . After the fun house , the player character has only one place left to search : the theater , located in King Cola ' s Castle . Cross the bridges , and enter the grounds of the castle . Fight to the top , and enter . Within , Oswald invites the player character to the theater , where he declares that his interest is piqued by their resilience . He teleports to the ground floor , shows off his ability to revive dead ghouls , then engages in battle . Oswald ' s weapon deals electrical damage and he will constantly revive ghouls that are killed in battle , while occasionally also using a stimpak . When his health is brought down , he will disappear , inviting the Sole Survivor to join him on the roof of the castle for one last match . Before leaving , check the rooms behind the stage , especially the one on the right , for the Nuka - Berry recipe , then take the elevator . Oswald the Outrageous . Upon arriving on the roof , meet the magical ghoul for the last time . This conversation can go one of three ways : either Oswald refuses to believe that a cure is nonexistent and attacks ; he is persuaded to leave with a hard Charisma check ; if Bradberton was searched and Rachel ' s holotape was retrieved , one can give it to him , whereupon he will submit and leave . In any case , the player character is rewarded with the unique weapon Sword of Wonders , Oswald ' s tophat and if Oswald is killed , his outfit . From here the park can be assigned to a gang as part of The Grand Tour .
