Marcel the Shell with Shoes On

What would you do, in an Airbnb for you, where you thought you were alone, until a tennis ball did roam; then appears a little shell, puts you under his cute spell, seems he's been left and deserted, though he's charming and assertive; has the place all to himself, alongside Connie and her shelf, there was once a bigger throng, for unknown reasons they've all gone; so you start to record moves, capture chats and he approves, publish them for all to see, where they're gobbled up with glee; before you know it he's a star, people travel from afar, the search begins for family, does he find them - watch the movie.

An endearingly told tale about a shell called Marcel.
