Snowby eggs require temperatures below -40°C to hatch successfully. If Snowby eggs become warmer than this temperatures for more than a few hours, they'll melt into a puddle of water.
Snowbies are gigantic snowflakes that are about 1.2 meters in length but are as light as a small snowflake.
They are sometimes called Santa's Helpers because they fall from the sky with small presents in hand. Sadly, once you receive and take your gift, the Snowby flake evaporates into thin air. But because of the magic of Christmas, it is believed that Snowbies respawn among the cold, wintery snow clouds up above, only to fall again to deliver a new gift.
They are among the greatest spreaders of Christmas cheer.
