Iva eggs are a blooming flower egg that blooms only in the month of December.
Ivas are praying mantises that develop the ability to fly. Their wings and their foot pads maintain the red color of their egg. No two Iva colors are alike—they're always some shade different than another.
Some say that the silently-flying Ivas are actually Santa's helpers and are the creatures that are able to keep watch of whether or not children have been good or bad. ("He sees you when you're sleeping, he knows when you're awake...") So, if you want some good Christmas presents, never be unkind to an Iva!
