"Don't sneak any goo berry pie."

"Don't sneak any goo berry pie." is a quote said at Pinkie Pie's bakery.

Origin
One night of September 2011, Kai snuck into Sugar Cube Corner. One minute later, he heard a voice whispering "Don't sneak any goo berry pie.". Then the moment he heard that he slowly crept down to where the Goo Berry Pie is. When he tried to reach it it fell down and splat, the pie was all over him.
