Hey guys, I think I just noticed something odd... that you all probably noticed months ago, so excuse me for being slow:
In "Party of One, " when Pinkie Pie is holding the party with her imaginary friends... exactly what room is she holding the party in?
Item 1 - Its clearly established throughout the ep that Pinkie Pie's room is on the top floor... but when Rainbow Dash enters, she's clearly entering through a door that's on the
ground floor (notice her wings are folded, you can hear her hooves tap, and the buildings in the background—obviously she's not flying).
Item 2 - When "Rocky" tells Pinkie that its a great party and she's outdone herself, you can see the corner of what looks like a stairway going up. Yet in at least two shots during the "party" we can also see the stairwell Pinkie came up at the beginning of the episode.
Item 3 - The room has a bed and a clothes closet, clearly indicating a bedroom... but in one shot we see it has a fireplace. Quite an unusual thing to have on the second storey, and in a bedroom (most houses put these in the dens).
So... what room is this? Pinkie's bedroom? Some weird sort of party room that has bedroom-esque furniture laid out in case one of the guests gets sick? Or some strange hyperdimensional room created by the sheer wierdness of Pinkie Pie's presence? You decide!
