I never would have thought of Rainbow as Bob Cratchit, Fluttershy seems more appropriate for that role.

Snowdash: Is that a magic cauldron?
 
Snowfall Frost: “Magic cauldron”? what kind of iodiocy is that? I’m not a sorceress! I’m just making a stew!
 
Snowdash: so, you are not planning to destroy Hearth’s Warming with a magic spell?
 
Snowfall Frost: Of course not! I don’t want to make the holiday go away, and I know it won’t go away! I just want to endure it, that’s all!
 
Snowdash: Anyway, I was meaning to ask you…
 
Snowfall Frost: You want the day of tomorrow?
 
Snowdash: It would be quite convenient…
 
Snowfall Frost: It’s not convenient, and it’s not fair! If I was to stop a crown’s worth for it, you’d think yourself ill-used. And yet, you don’t think of ME as ill-used when I pay a day’s wage for it.
 
Snowdash: It’s only once a year…
 
Snowfall Frost: A poor excuse for picking a Pony’s pocket every twenty-fifth of December! I can you give you the whole day today, but you must be here earlier tomorrow!
