Lyrics from mlp wikia : My name is Pinkie Pie (Hello!) And I am here to say (How ya doin'?) I'm gonna make you smile and I will brighten up your day It doesn't matter now (What's up?) If you are sad or blue (Howdy!) 'Cause cheering up my friends is just what Pinkie's here to do 'Cause I love to make you smile, smile, smile Yes I do It fills my heart with sunshine all the while Yes it does 'Cause all I really need's a smile, smile, smile From these happy friends of mine I like to see you grin (Awesome!) I love to see you beam (Rock on!) The corners of your mouth turned up is always Pinkie's dream (Hoof bump!) But if you're kind of worried And your face has made a frown I'll work real hard and do my best to turn that sad frown upside down 'Cause I love to make you grin, grin, grin Yes I do Bust it out from ear to ear let it begin Just give me a joyful grin, grin, grin And you fill me with good cheer It's true some days are dark and lonely And maybe you feel sad But Pinkie will be there to show you that it isn't that bad There's one thing that makes me happy and makes my whole life worthwhile And that's when I talk to my friends and get them to smile I really am so happy Your smile fills me with glee I give a smile I get a smile And that's so special to me 'Cause I love to see you beam, beam, beam Yes I do Tell me what more can I say To make you see That I do It makes me happy when you beam, beam, beam Yes it always makes my day Come on every pony smile, smile, smile Fill my heart up with sunshine, sunshine All I really need's a smile, smile, smile From these happy friends of mine Come on every pony smile, smile, smile Fill my heart up with sunshine, sunshine All I really need's a smile, smile, smile From these happy friends of mine Yes the perfect gift for me Is a smile as wide as a mile To make me happy as can be Come on every pony smile, smile, smile Fill my heart up with sunshine, sunshine All I really need's a smile, smile, smile From these happy friends of Smile, smile, smile, smile, smile Come on and smile Come on and smileeeeeee
