Arthur's birthday unluckily falls on the same day as his friend's, and he worries no one will show up at his own party until a solution occurs to him in the nick of time.
Arthur tries valiantly to save his sister from being disappointed when Mary Moo Cow, slated to entertain at D.W.'s birthday party, cancels at the last minute.
It is Muffy's Spring Fling party, and Arthur is so slow that he comes in last in every game--except for the jelly bean hunt, where not finishing early proves to be an advantage.
