Snowflakes were introduced as a new gameplay mechanic in New Leaf. Some larger snowflakes occasionally appear during December, January, and February when it is snowing. Though they may also appear even if the weather is clear and if a Snowmam is present in the town. They can be caught with a net and traded to Snowmam for Ice furniture. They can also be sold to Re-Tail for 500 Bells. Snowflakes cannot be stored in storage units, placed as furniture or dropped outside. When the player is outside they have the option of either showing it off, as if it were a catch, or throwing them away permanently.
Snowflakes make a quiet twinkling sound when in vicinity of the player.
