Sunny and her friends go on adventures and live life, and their friendship grows as they learn to understand each other’s differences and deal with various challenges. Meanwhile, the immortal alicorn Opaline, weakened and forgotten by the world, desires to take all the magic in Equestria for herself and rule the land. She sends her unicorn assistant Misty, who knows little about the world outside Opaline’s castle, to spy on Sunny and her friends in furtherance of Opaline’s plans. Misty is rarely successful, but sometimes finds herself enjoying life in Maretime Bay and begins to discover that the outside world is broader than Opaline has told her.
