With the sea teeming with colorful and fascinating animals, Fluttershy couldn’t help but explore the waters around the beach.
There, out of sight of her friends, she had a most unexpected encounter. A consortium of extremely friendly and curious octopuses.
Giving her no chance to escape (not sure she even wanted to), the molluscs grabbed her and greeted her in their own way.
Their skilled tentacles soon raced over her body, giving the most ticklish sensation.
Of course, the Fluttershy creature lover didn’t feel scared or angry. It was just fun (and rather pleasant) games with new aquatic friends.
