Jack-in-the-Box

Origin
Part-way through their adventures (and immediately after meeting the Golliwogg), Peggy and Sarah Jane Deutchland come across a box. Unsure of its contents, Peggy stands back as Sarah Jane attempts to open it. When she is successful, and Jack pops out, Sarah Jane is so frightened, she is knocked off her feet, causing Peggy to laugh.
