So anyways, in Rainbow Rocks, Pinkie and Flutters have a moment:
Pinkie: *Referring to poster* It smells like cake!
Fluttershy: It does? *Sniffs*
Pinkie: I used frosting instead of paste!
and so I thought, What if Pinkie did that, but with cake?
Pinkie: *Gives cake to Andrea*
Andrea: *Begins to eat*
Pinkie: It tastes like paste!
Andrea: *Eye widen*
Fluttershy: It does?
Pinkie: Yup! I used paste instead of frosting
