Every Girl's Fantasy, Now A Reality.— Giddyup Buttercup poster

Giddyup Buttercup is the name of a robotic toy horse manufactured by Wilson Atomatoys before the Great War. Touted as the "ultimate in equestrian robotics," it was a toy aimed at a target audience of little girls with a cost of $16,000. A marketing poster featuring the horse is copyrighted 2042.


The aliens aboard Mothership Zeta possess a large number of them stacked on racks in the research lab. One particular observation room has a lone Buttercup in the center surrounded by five dead test subjects.[Non-canon 1]

Alien captive recorded log 21 features Sally being taken to the recording room and noticing a Giddyup Buttercup. The aliens are described as being excited, either by her recognition of it or by her happy reaction. If Paulson, Elliott Tercorien, or Somah are taken to the Buttercups in the research lab, they'll make comments about them.[1][2][3]


  • In the Mothership's research lab are 109 Giddyup Buttercups. Smaller Buttercup toys can be found in four places on the ship.
  • A single Giddyup Buttercup is located just above the location of the smaller Buttercup toy in the engineering core.


Giddyup Buttercup appears in the Fallout 3 add-on Mothership Zeta.



  1. Paulson: "Why look at what we got here. Little girl here ridin' one of those horses. Giddyup Buttercup...kind of catchy ain't it?"
    (Paulson's dialogue)
  2. Elliott Tercorien: "Hey look, Giddyup Buttercups! All the rich kids had them. Waste of money if you ask me."
    (Elliott Tercorien's dialogue)
  3. Somah: "You've got to be kidding me... I saw posters like these all over the ruins. Never actually saw one 'til now."
    (Somah's dialogue)


  1. Fallout 3 Official Game Guide Game of the Year Edition p.710: "A deactivated Giddyup Buttercup lies motionless with “test subject” corpses strewn around her! It appears that Giddyup Buttercup could be programmed to inflict horrific damage on the squishier parts of human anatomy! With this shocking revelation still fresh in your mind, drop down into the Buttercup warehouse. The horsies are all full-sized except one Buttercup Toy on the end of a shelf on the west side of the warehouse. Shoot it to knock it down if you want it. Then head north, back to the lower production chamber, and back around to the initial production facility. Exit the way you came, or better yet, via the Teleportation Matrix in the test room where the corpses lie. Activate the control to open the door you couldn’t initially open when you first entered the Cargo Hold, allowing you to access the Engineering Core quickly."
