Once upon a time, there was a little fish named Fin. Fin loved to swim in the big blue sea. One day, while swimming, he met a friendly crab named Carl. Carl had many legs, but he could not swim like Fin.
"Hi Carl," said Fin. "I love to swim. Can you swim too?"
"No, Fin," replied Carl. "I can't swim, but I can walk with my legs. They are very reliable."
Fin had an idea. "Why don't we play a game? I will swim and you can walk. Let's see who can reach the other side of the sea first."
Carl agreed, and they started the race. Fin swam as fast as he could, and Carl walked with his reliable legs. In the end, Fin won the race, but they both had lots of fun. From that day on, Fin and Carl became best friends and loved to play together in the big blue sea.
