That is good to knnow my dear ;)  
I even have more ideas in mind that could add to this scenario.

Once it’s time to unwrap them they will need a bath if they’ve been under there for days (seeing as how Fluttershy’s gag says to open on Christmas Eve they must’ve been put there before then). Unless there was some sort of Christmas (or chaos) magic involved, of course.

@Setsugekka  
Ooh! That’s definitely the kind of teasing I’d like to get

@Little Ribbon  
Trust me when I say, I would be that kind of person. This is the kind of teasing I like to give. If the person under tree would be my partner, I’d even wonder where they’d be the entire time xD

@Phantom Rider  
I don’t think I’d have nothing to do, the recipient might be one of those people who likes to feel and squeeze and grab at their gifts while trying to guess what they are. Even if it’s obvious, they could still act like they don’t know

@Phantom Rider  
That’s true. Of course, the same thing would happen standing inside a snowman for two days straight. If nothing else, how could Rainbow Dash stand the boredom?

Best present ever!

@Little Ribbon
 
After spending most of the day tied there with nothing to do, you might get really bored…

@Little Ribbon  

 
I guess that means they were put there at LEAST one day before. :P

@Little Ribbon  

 
Just ask nicely and I bet that can be arranged. There’s always christmas next year ;)

@Little Ribbon  
I wouldn’t mind being put in this situation either.

I NEED those wrapping paper print footie PJs! So super cute!  
I was so into this even before the “Do Not Open Until Christmas” prints on the gags. What a wonderfully fun touch!
 
I want to be in this situation so SO MUCH! What’s a girl have to do to get gift-wrapped and set under the tree anyway
 
Edit: I just noticed Fluttershy’s gag says “Do Not Open Until Christmas Eve”, guess she’s the one you get to open the night before

@Harakiri  
Now that we’re on the subject, their pajama pants will be wet for sure if placed there on Christmas Eve. If they’ve been there for a few days, they’ll probably be more than just wet.
 
If you’re into bondage but wetting is a turn-off, you could just say a common anomaly of fiction applies like when the Main 6 were locked up by Starlight for days and EqG Rainbow Dash spent two days as a snowman, all without needing to pee once (well, we’re not so sure about Rainbow), though of course I’ll think otherwise in my headcanon (whatever the story of this image is).

@Harakiri  
Depends on when they are bound.  
if it was the night of the 24th then not that messy.  
but had they spent a week or more stored somewhere before being placed at the tree….you have me there.

They must have messy pants after days they have been bound under the tree.

I like this, If I found them like this I get some good help with them  
_{As long as they like to be my slaves that is.}

How long are they gonna be there before they’re “unwrapped?” (A.k.a. when were they put there?)

There’s no need for tears girls. I promise I’ll take good care for all of you.
