A Chinese merchant who refused to be converted to the Christian faith while passing in front of the monastery of Guadalupe was almost caught by the devil disguised as a caiman to devour and bring to hell.

Yet despite his being Pagan, he called to the saint venerated in the monastery, calling loudly, "San Nicolasi, San Nicolasi" and in uttering this prayer, the crocodile marvelously turned into stone and left the merchant safely.

Due to this miracle, the Chinese merchant converted to the Christian faith and in thanksgiving erected an ermita near the petrified caiman.

even noted the immensity of the celebrations that "more than a thousand kilos of candles were offered during these devotions."

However, nothing remains of these devotions to San Nicolas de Tolentino with the petrified crocodile, popularly known as the buayang bato cemented over in the 1970s to beautify the Pasig, the old ermita ordered demolished and the image of the saint moved to the monastery in Guadalupe.
