First, let's start with Merry Noel.

Merry Noel is the best at making you feel very, well, merry all year long! On Christmas Eve, she wishes everypony a good night. Throughout the night, she helps Santa deliver presents to all the good little fillies and colts. Then on Christmas Day, she strolls throughout Equestria singing Christmas carols.

Next is Holly:
Holly is what you might call a pony on the "nice" list. Even when it's not Christmas, she is always lending a helping hoof and handing out presents. Being the sister of Merry Noel, she has met Santa Claus and even helped him deliver presents once!

Next is Snowflake Sparkle:

Beautiful, shy, and dainty as a snowflake, Snowflake Sparkle is in charge of making all the beautiful snowflakeyou see in the winter time. She loves having lots of friends, but sometimes needs a little help introducing herself. Because of her extremely shy ways, other ponies often wonder if she is the sister of Fluttershy. But every time she is asked this question, Snowflake always answers "No." or "Who's Fluttershy?" She may seem like the kind of pony you would want to avoid, but once you get to know her, she is one of the kindest ponies you will ever meet.

Next is Candy Cane Twist:

"Hey everypony!! Watcha got there? Is it fun? What are you doing today? Want to go to the pool with me? Ooh, look! A butterfly!! Are you excited for Hearth's Warming Eve to come?!"
This can only be the excited little voice of Candy Cane Twist. She's super duper energetic and is always bouncing off the walls. She's great at making delicious Christmas candy, but always puts a little too much sugar in her treats. When questioned about this, Candy always answers with a smile, "I think around this time of year, I should make everypony a little more... SWEET!!"

Finally we have Gift Wrapped:

Who do you think wrapped that perfectly wrapped present under your Christmas tree? Not Santa. Not the elves. Not your grandma... So who DID wrap that perfect present? Why, it's Gift Wrapped, of course! Gift Wrapped is the best at wrapping presents. For birthdays, holidays, or even graduations, if you want your presents wrapped perfectly, Gift Wrapped is the mare for the job. She always makes sure her presents get to other ponies' homes with care. On Christmas morning, all the fillies and colts and their mothers and fathers are all amazed by the wonderful work of Gift Wrapped!
