Museo de los Muñecos / Museum of the Dolls (fictional)

The Museo de los Muñecos appears in a Spanish-language summary of an R. L. Stine Pesadillas story as the attic doll collection of Trina O'Dell's family. The narrative identifies the collector as Trina's father, a former ventriloquist, and describes the attic storeroom as being nicknamed the 'Museum of the Dolls.' In the literary synopsis, paranormal-like occurrences begin in the attic: voices are heard and the dolls repeatedly turn up in strange places as if they had moved on their own. No named spirits, traditional entities, or investigative findings are provided in the source material — the phenomena are presented as elements of a juvenile horror plot rather than documented real-world events. The provided source set includes other items (a Wikipedia excerpt for Puebla de Zaragoza, a video/listicle of unusual museums, and a magazine issue) but none corroborate the existence of a real Museo de los Muñecos in La Plata or elsewhere. Per the research notes, any geographic attribution to La Plata, Argentina, or Puebla, Mexico, is unsupported by the excerpts; therefore this entry treats the site as a fictional private/attic collection described in literature.
