Poosophagus, also known as Unko Tin Tin (ウンコティンティン) in the Japanese version, is the guardian of Faudo's Esophagus.
Appearance[]
Original Unko Tin Tin
Unko Tin Tin is a massive internal guardian of Faudo. Its head is skeletal in structure, encased within a transparent capsule that protects its exposed brain. The creature’s arms and chest are reinforced with thick, bone-like structures that twist and entangle around its frame, giving it a grotesque, armored appearance. Around its collar is an ornament resembling a cow’s horn, a design feature shared with Faudo itself, further linking it to the giant’s inner defenses. Unlike a complete humanoid form, its lower body is unfinished; instead, the torso is fused into the wall, making it an immobile sentinel. Despite this limitation, its sheer size is daunting—its upper body alone towers several meters high, comparable to the colossal “Heart Beating Demon” that also dwells within Faudo.
Personality[]
Unko Tin Tin embodies a strange contrast between his role and his behavior—loyal as a gatekeeper, but childish as an individual. In his duty within Faudo, he shows a rigid sense of responsibility, strictly enforcing trials and never wavering from his role. Yet, his personal demeanor is petty, emotional, and self-centered.
During Kiyo’s trial, he reacted irrationally to the reasonable remark that the questions seemed straightforward, lashing out with hostility and insults such as “garbage bug” and “I don’t like him.” He then deliberately posed difficult questions out of spite, continuing to harbor resentment against Kiyo long afterward. Despite his bluster, however, he is easily shaken; when mocked for being unable to handle simple calculations compared to solving Fermat’s Last Theorem, his bravado quickly collapsed, leaving him teary-eyed and exposed as childish.
This immaturity may stem from his isolated upbringing as an internal monster. With no real social contact beyond the family that constructed Faudo and Riou, he never developed the social growth or perspective of a human. Even so, he demonstrates moments of integrity: he honored his promise during Megumi’s trial by changing the challenge to something Ponygon could solve, and when defeated by Wonrei, he accepted his fate and committed suicide without hesitation. These contradictions highlight him as both petulant and conscientious—an immature being shaped by circumstance, yet unwavering in his duty as a guardian.
Biography[]
Background[]
Unko Tin Tin is one of the many internal monsters created within Faudo’s body, serving as the so-called “Gatekeeper of Knowledge.” Stationed at the passage within Faudo’s mouth, he was tasked with testing all intruders by forcing them to answer riddles and questions, with failure resulting in being dropped into Faudo’s stomach acid. Though designed as a guardian, his questions were usually childish, and his behavior was heavily influenced by immaturity and pettiness.
Part I[]
He first appears during Gash’s group’s infiltration of Faudo. While most of his challenges were simplistic, he singled out Kiyomaro, mocking and antagonizing him by assigning a six-digit multiplication problem. To his own frustration, Kiyomaro instantly solved it. Enraged, Unko Tin Tin escalated to demanding the impossible—Fermat’s Last Theorem. Kiyomaro humiliated him further by pointing out his hypocrisy, forcing him to change the problem. In return, he imposed a crude condition on Megumi, making her shout his name aloud. Despite his immaturity, he still honored his word when Megumi fulfilled the condition, allowing even Umagon to proceed after answering correctly.
When Faudo was revived, Unko Tin Tin underwent a transformation, gaining legs, massive size, and an array of powerful weapons. In this “Powered” state, he confronted Wonrei, initially defeating him due to Li-en’s absence. After Li-en’s arrival, however, the tide turned as she empowered Wonrei with spells, their coordination overcoming his brute force and disruptive tactics. Defeated, Unko Tin Tin chose to self-destruct in an attempt to take his opponents with him, but his plan failed. Wonrei’s resolve disrupted the explosion, and Unko Tin Tin perished in an ironic end, destroying himself without certainty of victory.
Anime[]
In the anime adaptation, his arc diverges. Rather than fighting Wonrei to the end, he is abruptly dispatched by Bari, who knocks him into Faudo’s magma with Zonis, eliminating him without further conflict.
According to Makoto Raiku’s blog, after Faudo’s return to the Mamodo World, Zatch rehabilitated many of Faudo’s internal monsters. Unko Tin Tin was possibly granted a normal-sized body and now attends school alongside others.
