Cheerilee looks downright delighted by what Pinkie Pie did with her tongue. The teacher looks so bright and happy that she doesn't even care that Pinkie graduated so many years... (Wait — Could it be...?) Pinkie Pike looks so adorably proud and happy that one can't help but smile with her. Maybe after she holds that expression for a few hours somepony will realize she needs help washing the lead-based paint off her tongue. And that foal is doing a pretty decent job with the flowers now that it's okay to use more than her hooves.
C'mon though! Let use see the picture that astounded Cheerilee!
