THINK ABOUTIT’S ALIEN TYPE SUMMARY
Mook
The Mook and the small being reported near Ririe, Idaho in November 1967 are two separate, independently documented cases that this page had previously merged into one identity without any source actually making that connection. The Mook’s own documentation is thin: a brief, secondhand description of a small, “hungry” creature said to originate not from any single star system but from “several different parallel universes from the Multiuniverse.” The Ririe encounter is a real, well-investigated case in its own right — with its own distinct physical description — and deserves to be read on its own terms rather than folded into this entry.
Name: Mook
AKA: None documented. This entry has previously been identified with the “Ririe Entities” from the November 1967 Idaho encounter; no source reviewed supports that identification, and the two are treated separately here (see Related Cases).
Location – Home System: Undocumented as any single star system. The sole source located for the Mook states they come from “several different parallel universes from the Multiuniverse,” not from Antares or any other named star.
Distance from Earth: Not applicable — the source describes a multiversal origin rather than a location within this universe
Attitude: Undocumented beyond being described as a “hungry creature”
Motives: Undocumented; the source does not explain their apparent hunger or what, if anything, they consume
Physical Appearance: Small compared to Earth humans, standing about 4.3 feet (1.3 m) tall, with long arms and three fingers. They are said to wear “funny clothes,” with no further description given. No other physical detail — skin tone, eye description, or facial features — appears in the source.
- Average Height: About 4.3 feet (1.3 m)
- Average Weight: Undocumented
- Body Temperature: Undocumented
- Pulse/Respiration: Undocumented
- Blood Pressure: Undocumented
- Life Expectancy: Undocumented
- Hair: Undocumented
- Skin: Undocumented
- Eyes: Undocumented
- Sex: Undocumented
Other Physical Information: Long arms and three fingers; wears unspecified “funny clothes”
Special Traits and Abilities: Said to be able to “accelerate or decelerate” the frequency of vibration of their atomic structure, which reportedly allows them to exist within “our 3rd dimension.” How this was determined is not stated.
Communication Type: Undocumented
Origin: “Several different parallel universes from the Multiuniverse,” per the source — a multiversal rather than single-planet or single-star origin
Life Form Type: Undocumented formally
Subspecies: None documented
Most Common Species: Undocumented
Level of Species: Undocumented
Habits: Undocumented beyond being described as a “hungry creature”
Transportation Type: Undocumented for the Mook specifically
Witnesses Reports: None named. The source states its information was “recovered from crash sites,” without giving a location, date, or named witness.
Special Features/Characteristics: A reported ability to shift their atomic vibrational frequency, said to allow existence within our third dimension
Summary/Description: The Mook are a minimally documented species, attested through a single secondhand source that describes them as small (about 4.3 feet tall), “hungry,” long-armed, three-fingered beings originating from multiple parallel universes rather than a single star system. No named witness or dated event supports any part of this description, and no source establishes a connection between the Mook and the 1967 Ririe, Idaho encounter, despite past identification of the two on this site.
Source: Bibliotecapleyades website (“The Mook,” in Para-Terrestrial – Code: Paramus), as presented and reviewed in Jake Muller, A Guide to ETs/Star Nations and Beings (M–Z), Vol. 2, 2024, pp. 66–67.
Related Cases: The November 2, 1967 Ririe, Idaho encounter (witnesses Guy Tossie and Will Begay) describes a separate small humanoid — reportedly bald, with heavily creased or scarred skin, round pupil-less eyes, thin lips, and no visible nose — arriving in a small double-saucer craft with a transparent dome. This is an independently and extensively documented case, including on our sister site, thinkaboutitdocs.com, but no source establishes that this being and the Mook are the same entity, and their documented physical descriptions do not clearly match.
DETAILED REPORT
Very little can be said of the Mook with any confidence. The sole source located for this entry is a brief passage on the Bibliotecapleyades website, which states that its information was “recovered from crash sites” without specifying where or when. That source describes the Mook as originating from “several different parallel universes from the Multiuniverse,” able to shift the vibrational frequency of their atomic structure in order to exist within our third dimension — a claim offered without explanation of how it came to be known. The physical description given is limited to a height of about 4.3 feet (1.3 m), long arms, three fingers, a description of the beings as “hungry,” and a note that they wear unspecified “funny clothes.” No skin tone, eye description, or facial feature is given, and no witness or dated encounter is named.
This page had previously identified the Mook with the “Ririe Entities,” referring to a well-documented November 2, 1967 encounter near Ririe, Idaho, in which two young witnesses, Guy Tossie and Will Begay, reported being approached by a small being that entered their car after emerging from a domed, disc-shaped craft. That case is real, extensively investigated at the time by NICAP researcher C. Reed Ricks, and independently documented on this network’s own sister site, thinkaboutitdocs.com. However, no source located for either case actually identifies the Ririe being as a “Mook,” and the physical descriptions on record for the two differ in several respects — most notably, the Ririe witnesses described a bald being with heavily creased, scarred skin, round pupil-less eyes, thin lips, and no visible nose, none of which appears in the Mook’s own sparse documentation. The two are treated separately here pending any source that actually connects them.
RESEARCHER’S NOTES
The Mook — A Multiversal Sketch Wrongly Merged with a Documented Idaho Case
- Classification Correction: This entry previously placed the Mook at Antares (Alpha Scorpii) with a full biometric panel, named subspecies, multiple species-tier classifications (“Type 0.7,” “Level IV”), and a direct identity claim with the 1967 Ririe “Ririe Entities.” None of the biometric or classification detail appears in the Mook’s actual source, which instead describes a multiversal, not stellar, origin. The Ririe identity claim has been removed and the two cases separated.
- Source Chain Assessment: The Mook’s documentation consists of a single, brief, secondhand passage citing unspecified “crash site” recovery, with no named witness or date. This should be treated as one of the thinnest sources in this archive, not padded out with unrelated case detail to appear more substantial than it is.
- Pattern Context / Comparative Cases: This is the same misattribution pattern seen elsewhere in this archive (compare: Matrax’s misattributed “Independence Day” origin claim, Meta-Terrestrial’s incorrect Rendlesham Forest/Montauk Project links) — a real, separately documented case folded into an unrelated entry without a source actually connecting the two. The Ririe encounter deserves its own full treatment on its own terms, which this site’s sister archive, thinkaboutitdocs.com, already provides.
- Physical Evidence / Evidentiary Weight: The Mook itself has no named witness, date, or location on record. The Ririe case, by contrast, is comparatively well-documented, with named witnesses, a contemporaneous NICAP investigation, and law-enforcement involvement — but that evidentiary weight belongs to the Ririe case, not to the Mook, and should not be borrowed to lend the Mook entry false credibility.
What can honestly be said of the Mook is very little: a small, “hungry,” multiversal being described in a single thin passage with no named witness or date. The 1967 Ririe, Idaho encounter is a genuinely substantial case — but it is not established to be the same one, and each deserves to stand on its own documented terms rather than be merged for the sake of a fuller-looking page.
The Mook are said to originate from “several different parallel universes from the Multiuniverse.”
