I'll tell you the conditions of hugging a pink horse:



1- The pink horse must smell nice. Pinkie smells like cotton candy, so this works.



2- The pink horse must be friendly. Pinkie is friendly, so it works.



3- The pink horse must need/want the hug, or I must be in the mood. Pinkie needs it, which makes me in the mood to do it.



Conclusion: I would hug a pink horse.
