My Little Pony - Earth Pony - Bubbles - Collector's Item (1983)

Lemon Drop saw a strange, muddy pony galloping toward her from across the field. "My goodness, I think you need a bath!" she exclaimed as she poured her favorite bubble bath into the waterfall beside the stable. Soon bubbles were everywhere, twinkling in the sun and floating on the gentle breeze. "Perhaps I put in too much bubble bath," she thought. "Oh well, she really is very muddy." After much scrubbing a beautiful, yellow pony emerged from the bubbly water. "I'll call you Bubbles," said Lemon Drop. Bubbles just smiled. She had found a new friend.
