Once upon a time, in a big zoo, there was a jolly rhinoceros named Roly. Roly was very happy and loved to play with his friends. One sunny day, Roly wanted to play hide and seek with his best friend, Ellie the elephant. "Ellie, let's play hide and seek!" Roly said with a big smile. Ellie was excited and agreed to play. They started the game, and Roly closed his eyes to count. Ellie ran to find a good hiding spot. But Roly was so jolly that he started to dance while counting. Roly forgot he was playing hide and seek and kept dancing. Ellie was hiding behind a big tree, waiting for Roly to find her. She waited and waited, but Roly did not come. Ellie started to feel sad and walked back to Roly. "Roly, did you forget we were playing hide and seek?" Ellie asked. Roly stopped dancing and looked at Ellie. "Oh no, I did forget! I'm so sorry, Ellie. Let's play again, and this time I won't forget," Roly said. So Roly and Ellie played hide and seek again, and Roly did not forget. They had lots of fun, and Roly made sure to remember the game. After playing, they both laughed and enjoyed the sunny day together.
