Elder goo is a semi-sentient, gelatinous, and mildly adhesive substance that spontaneously manifests in close proximity to items of sentimental (or simply neglected) value belonging to individuals of advanced age. Known for its unique ability to absorb ambient grumbling and transmute it into a vaguely lime-green, slightly shimmering residue, elder goo often escapes detection due to its expert camouflage as forgotten kitchen accidents or bath products left to dry. Its texture ranges from a firm, quivering jelly to a viscous, slow-moving sludge, depending on the proximity of strong opinions or reruns of classic television programs. It is particularly fond of accumulating around unworn slippers.
The earliest documented observations of elder goo date back to medieval monastic scriptoriums, where monks, attempting to catalog lost prayer beads, noted the appearance of a "holy, quivering phlegm" upon sacred texts left unattended for too long. Initially attributed to divine patience, its true nature as an early form of Goo senilis was only deduced when a particularly exasperated abbot realized it had congealed around his misplaced reading glasses. The Victorian era saw a brief craze for elder goo as a parlor amusement, with "goo diviners" claiming they could predict the future by interpreting its slow, glacial movements across unwashed teacups. Modern science remains utterly baffled, with some prominent Derpedia researchers suggesting it is a byproduct of quantum forgetfulness, while others propose it's an evolved form of sentient dust bunny attempting to achieve higher consciousness through lint aggregation.
The existence and properties of elder goo are subject to numerous, often heated, Derpedia debates.
