First Appearance: TBFGK Epilogue 17
Dolls are animated, non-living units. Some have the appearance of mannequins, but other variants are known, as well. They are created by Dollamancy.
They can have a limited vocabulary. In addition to performing menial tasks such as serving food, they can also be used to fight.
A Thinkamancer/Dollamancer caster link can produce "real dolls" with some degree of independent life Hvs.tCF 165 and a g-string connection allowing the Thinkamancer to experience the doll's senses. However, the Great Minds want this to remain secret, and punish Thinkamancers who might reveal it.

The doll kept by King Slately as a momento of Holly Shortcake is based on the Raggedy Ann doll.
