This cute picture is about pinkie pie tickling fluttershy's belly with her hooves. So when pinkie pie and fluttershy was spending some best friend time together, pinkie pie forgot about the last time she saw fluttershy laugh. Pinkie pie caught an idea and then asked fluttershy to lay on her back. When she did, pinkie saw her chance and started tickling her belly. Fluttershy started squealing with laughter as her sensible tummy was getting tortured.

Pinkie pie: coochie coochie coo~

Fluttershy: squeals pinkie please, not- HAHA not my belly!
