A digital illustration of STRAWBERRY REEF, a pink earth pony from My Little Pony's third generation. She has a light pink body, hot pink hair with tinsel throughout, and green eyes. She's sitting in the sand on the beach, looking happily at a sand castle, which is being occupied by a crab and hermit crab. Sand toys are scattered near her. The sparkling ocean, clouds, and birds are all behind her, the sun shining onto the landscape. Text reads @sparkytopia with a heart.

Strawberry Reef is building sand castles on the beach... it looks like her friends like them! I've had some beach pony sketches rattling around in my travel sketchbook for a few weeks, it was only a matter of time until I picked a pony for them to be and finished it. I chose Strawberry Reef here because of her lovely pink color- she doesn't disappear into the scenery like a yellow or blue pony might! Thanks for looking!
