El cangrejo que vino a cenar

Stew, Wolf, and Tortilla have gone to spend a few days at a cabin by the sea. The beach is great, and the sea is lots of fun, with its waves that come and go. Suddenly, Stew finds a small pebble…that runs away. It's a crab! A rather strange one, who seems to cause a lot of trouble. Perhaps he's just looking for friends?
