Twilight takes her and her friends through her inter-dimensional portal to discover new possibilities (although Pinkie Pie has already done all that).
When they reach the other side and find very little, they return home a bit disappointed.
However, this will reveal something about Equestria that I'm sure none of us would like/find a little annoying.
NOTE: this story has a random build up to it that lasts a while but I tried to make it entertaining (if I didn't do this then the story would be really short). And it's not so much about anyhing in particular, just another random idea I had that I wrote instead of sleeping.
WARNING!!! This contains tickling induced urination.
