This egg was only available in Egg Cave's Cash Shop Park for Christmas of 2014.
Golosina eggs look an awful lot like peppermint candies. But these eggs are for hatching, not eating!
Golosina are expert Christmas tree decorators, particularly with Christmas ornaments. Their wings allow them to fly to places in your home that you might not be able to reach yourself. Additionally, they have great dexterity with their tails which allows them to multitask a decent amount.
In terms of mood and temperament, Golosinas are very cheerful creatures especially around Christmas. It's a very rare thing to see a sad Golosina.
