Original Description:
 
Darky walked along the beach while there were few ponies on it and no one stepped on her. The weather was pleasant enough, the sand was warmed up by the sun, and the water was noisy nearby. True, Darky did not notice that macro Chrystal was walking behind her, who did not really look at her feet and did not see Darky at first, but as she got closer, she still noticed a dark creature walking carelessly forward on the sand. Then she began to stomp harder on purpose, coming closer and closer. Darky felt it and looked back to see Chrystal rapidly approaching, dangerously stomping on the sand with her feet. Frightened, the dark pegasus immediately ran away until she was trampled. But after a couple of moments, she found herself in Chrystal’s shadow. Looking up, she saw a huge, pale blue foot from which sand was falling directly on the pegasus. Not looking down, the running Darky stumbled and fell on her stomach. Wasting no time, she began to crawl forward. Chrystal watched this with a smile for a while with her foot raised above this tiny pegasus, until she abruptly stepped on her, while denting it in the sand and playfully saying “Oops~”. Suddenly seeing another tiny blue pony in front of her, Chrystal immediately turned her attention to him and walked with Darky stuck to her sole. Meanwhile, the gray pegasus was trying to somehow free herself, but the foot immediately nailed her harder with each stomp, temporarily disorienting and knocking her breath away. Coming close to an unfamiliar stallion, Chrystal also lifted her foot over him, but with Darky stuck to her and without ceremony also stepped on and went on, leaving the stallion trampled into the sand, and Darky stuck to her foot
