So they were working away, talking of different things, and Nellie was a great help to Mrs. No-Tail. Every once in a while, however, Nellie would look over to the cake, because it was so nice she just couldn’t keep her eyes away from it. She was just wishing it was time for her to have some to take home, but it wasn’t, quite yet.

Well, all of a sudden, when Nellie looked over for about the twenty-two-thirteenth time, she saw that all the chocolate was gone from the top of the cake. All the chocolate and the cocoanut was missing.

“Oh! Oh!” cried the little sparrow girl.

“What’s the matter?” asked Mrs. No-Tail quickly.

“Look!” exclaimed Nellie, pointing to the cake.

“Well, of all things!” cried Mrs. No-Tail. “That chocolate must have disappeared. It must have gone up like a balloon. I will have to buy some more of you, and put that on.” Then she went over and looked at the cake, and she wondered at the queer scratches in the top, just as if a cat had clawed off the chocolate. But there were no cats around.

So Mrs. No-Tail and Nellie put more chocolate and cocoanut on the cake, and they went on washing up the dishes, and pretty soon, not so very long, in a little while Nellie looked at the cake again. And, would you believe me, the chocolate was all off once more.

“This is very strange,” said Mrs. No-Tail. “That must be queer chocolate to disappear that way. Perhaps a fairy is taking it.”

“Maybe Bully and Bawly are doing it for a joke,” said Nellie. So she and Mrs. No-Tail looked from the window but they could see no one, not even a fairy, and, anyhow, Mrs. No-Tail knew the boys wouldn’t be so impolite as to do such a thing.

“It is very strange,” said the frog boys’ mamma. “But we will put the chocolate and cocoanut on once more, and then we’ll watch to see who takes it.”
