One morning Sylvia wakes and remembers a curious dream.  In the dream she helps a group of little ants, and in return, they give her some 'friend cake'.  And what is friend cake?  She doesn't know at first, but after wondering about it for a while, she, Martin and Momma decide that they need to bake a 'friend cake,' and give it to their dear friend Miss Melinda of the Spunderful Shop.  When they arrive later that day, however, they realize their friend cake is not only for old friends, but for new friends too!
