"Crabby is not a happy crab, in fact Crabby is quite crabby, so pushy Plankton, who is always trying to cheer up fellow marine creatures, bakes Crabby a cake--but will Crabby finally smile?" --

When Crabby gets sick, Plankton is determined to play doctor and take care of his friend, even if Crabby does not want the help--until Crabby realizes that he can get Plankton to do all of his household chores.

It is late and Crabby just wants to sleep, but Plankton keeps Crabby awake with questions and chatter--until a request for a bedtime story takes an unexpected turn.
