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, suggesting the toy was sold at least in that year.
The aliens aboard Mothership Zeta are shown to have an unusual fascination with the toy, possessing hundreds 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. Blood stains on the glass tube in the center and the floor suggest that the group was attempting to flee something in vain, ostensibly the seemingly harmless toy.
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 several uneasy comments about them.
- In the Mothership's research lab are 109 Giddyup Buttercups stacked all over. 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.
