Fatfoot: Encounters with a Dooligahl is a quintessential cryptozoology investigation. Neil Frost has spent decades investigating and interacting with the phenomenon of the Australian Hairy Man, developing an intriguing thesis regarding the mammalian identities behind Yowie encounters.

Based on observed behavior and biology (both personal observations and those of his community network, nicknamed The Octopus), the author reasons that there are three distinct species involved, all as-yet-undescribed marsupials. Fatfoot introduces us to the Dooligahl, the aggressive Quinkan, and the monkey-like Junjudee.

The author's thesis asserts that 'manlike' or 'apelike' characteristics are due to evolutionary convergence, noting that similar biological parallels are found with many other Australian marsupials and their placental lookalikes. In an eminently readable history of his growing awareness of these mystery animals, the author lays out the evidence he has obtained, discusses the issues with gathering evidence (especially at a time when technology was expensive and difficult to obtain), and builds a foundation for future investigation.

As a personal record of the author's coming to terms with an inexplicable animal in his own backyard, and ongoing search for scientific answers, Fatfoot serves to inspire both zoological and indigenous anthropological research. .
