mga engkanto are attracted to laughter, that much I know. I've heard also that if you walk around a suspected spot 9 times under a full moon, it could reveal a portal to their world. Also, children are madami likely to see these little creatures, especially girls (from what I've head). This is information I already knew and some stuff I looked up earlier about fairies. Hope I helped! :)
Most mga engkanto are wise and clever and you will have trouble finding them. You'll have better luck catching pixies, who are madami playful and silly. They're the small ones. But since mga engkanto live in Fairyland most of the time you probably won't be able to find one. Pixies are madami likely to come to the real world, but other mga engkanto are naturally curious and might also come her on occasion, but they'll be madami cautious than pixies.
