I would like to nominate the Sea Turtle as a Critter. These are endangered and thought by making turtles a critter, it could be offered for sale and then a portion of the monies could be donated to any Turtle rescue organizations.
From a commercial stand point, Mother Sea Turtles shown with their babies after hatching - caption could be something to do with long distance and having a large family living apart.
This could be done for any endangered species made into a critter for sale.
