Crabby Christmas is what every child at Christmas goes through at one time or another with unwanted relatives coming to stay and upsetting their special time. However this Christmas Eve is saved from disaster coming in the form of a box full of little Hermit Crabs. These little guests were supposed to be delivered to a nearby pet store, but surprisingly wind up coming to the Crabtree house for a Christmas Eve full of surprises, and turn the tables on the uninvited guests (the unwanted relatives I mean).
