PINKIE PIE AS SHERLOCK DISCUSS

 

[No Lynch]

Pinkie's the culprit. Pure obviousness.

...

If not, it's Celestia's fault.

 

[hurristat]

If it's my fault, then I guess no one's getting punished.

 

[SaixBanana]

Obviously Trixie will be the culprit. We've already been given the hint.

 

[Oblivion]

*sigh*

Only Pinkie would put up this much of a fuss over a cake. Though, at this point, I guess it's only to be expected.

 

[Goodbye Blue Monday]

I'm putting my money on Pound Cake.

 

[SolgaleoGX]

Cadence. This has to be that dark secret she's hiding.
