The way Pinkie has her eyes closed, she could miss the surprise anyway. And, if she suddenly releases, she could end up ruining the surprise.

I’ll never look at brown icing bags the same again! XD  
Great metaphor, though. Let’s hope it catches on.

@PUBLIQclopAccountant  
Lol, yeah

@asperman1  
Manure and lemonade?

@Ithinkitsdivine  
well, to wait

@Ithinkitsdivine  
Just wish both were leaking, lol

@asperman1  
Thank you.

No comic this time. Maybe I can revisit these pics in the future and do follow ups, but that Rainbow Dash comic was kind of a one time thing. I’ll do more long form stuff in future.  
@SinnerWhoKeepsTrying1978  
That would be the sensible thing to do. But Pinkie and Apple Bloom aren’t exactly known for being sensible are they? Oh, and yeah, I’m pretty proud of the idea of representing the need to poop with an icing bag. I’d never seen a metaphor for full large intestines before so I had to come up with something myself.

Finally, I’ve always wanted to see Pinkie’s urge to make chocolate icing.

At this point, Applebloom could volunteer to delay the surprise until Pinkie goes and empties her bowels and bladder, then returns. Otherwise, every one there’s going to be in for a less pleasant surprise.
 
@Ithinkitsdivine  
Considering chocolate and poop are generally the same color, I’d say that a bag full of chocolate icing is perfect for representing full large intestines.

I wonder ,if it will make  
a comic of pinkie?  
well is a question cosmic

would drink her cider

@Ithinkitsdivine  
Upvoted that as well, indeed funny.

Nice pic

@Soctavia  
That is indeed what those mean. I’ve added an alternate version for people who don’t like chocolate icing though.

@Lynx318  
I think those are a metaphorical representation of a full bladder and full, uhh… bowels…

Brown icing bag, thought this might be going somewhere else til checked the tag for the other object. Who is doing the magic around the items?
