Two boxes -- one large, one small -- arrive for Granny Lambert. But wily Belzoni, her cat, sees the note printed on the small box that reads: Don't Open that Box, Open this one first! Unfortunately Granny doesn't notice the sign and opens the big box. Out jumps a crocodile, and snap, snap, snap, Granny is gone. And Belzoni is next on the menu.Suddenly out of the box jumps a chicken, and with her help Belzoni soon gets to grips with the hungry croc.
