...that's very probably gonna pop up as the preview image for some sorta crack fic.
I can already picture part of the plot; It's like "The Fly", except with a lobster. Twilight teleports Applebloom and a lobster by accident, cliché #3 takes place (aka "Twilight Sparkle messes up a magic spell, providing the basis for the entire story"), and the result is what we see in the above picture.
... I wonder what the lobster's cutie mark would be?
