Boobies be praised!

@BrownieComicWriter  
Thank you, Boobies.

@Background Pony #1F7E  
Boobies! :D

@BrownieComicWriter  
That’s a shame.I was very scientific by some definition.

@Background Pony #1F7E  
tl;dr

@BrownieComicWriter  
Yes but its all countered by her extremely efficient metabolism (after all breaking the laws of physics requires a lot of cupcakes)in fact her intake is so much as well that instead of a balance ,it creates a unique digestive phenomenon in pinkies body that producedes fat based lumps on her chest that while at firstvglance may seem like mammary gland but are in fact her body attempting to store sugar and fat on her chest as opposed to her hips or so. Her “size”as it may be varies with what she does and how much she eats on a greater scale than a normal female as this mutation is unique to this little pink hole in logic of the universe.

@Background Pony #1F7E  
Wouldn’t eating something sugary and fatty like doughnuts do just as well in growing her some boobies? :3c

@BrownieComicWriter  
That would involve limiting her sugar intake,and when that happens well…  

@Background Pony #1F7E  
So why shouldn’t Pinkie Pie?

@BrownieComicWriter  
Because a lady like Rarity has taken a specific culinary diet and strict nutritional measures to ensure that her body sprouts a set of proper female mammary glands.  

@Background Pony #1F7E  
Well why should Rarity be any different?

@BrownieComicWriter  
That’s different!Those aren’t lumps of fat,hers are lumps of in digested sugar,trying to escape her cavernous bowels.

@Background Pony #1F7E  
What about Pinkie Pie?

Am I the only one wondering why rarity the the only one with tits?
