Singlish is a Water-type creo obsessed with digging holes in the ocean floor to find sunken treasure.
Around people, Singlish are shy but utterly captivated by even the smallest trinket. Divers sometimes see one dart toward a piece of reflective gear and then retreat. They are hard to keep in captivity, because confinement dulls their curiosity and they lose interest in eating.
Biology
Singlish is easy to miss from above, since its powder-blue scales blend into the sunlit water over the reefs and seabeds where it lives. Seen up close underwater, a Singlish usually has flecks of dirt and sand dulling its faint shimmer.
Singlish live on small crustaceans, mollusks, sea worms, and any edible scraps they turn up while digging.
Singlish have an 18-year lifespan. They get around by paddling close to the seafloor, using their fins to dig, glide, and disappear into clouds of sediment.
Singlish live in coral reefs known for their bright, many-sided, reflective structures. Those reefs shelter them from predators and constantly feed their attraction to anything that glitters. Singlish sift tirelessly through sand and sediment looking for lost coins, polished stones, broken relics, and naturally reflective shells. The objects are of no practical use, but Singlish instinctively hoard them in hidden burrows under the reef. Oddly, they are not possessive about those hoards at all. They do not seem to mind coming back to find the whole stash plundered, and they cheerfully start over.
They are peaceful and never aggressive, and other creo tolerate them, since they threaten nothing and help aerate the seabed with all that digging. Singlish do not migrate far, usually staying inside one reef system for most of their lives.
