LaPetite first appeared in frames 799 to 802. She also appeared in frame 951, in frames 968 to 970, and frames 3036 to 3077.
She had the idea to convert the wooden frame of the sandcastle into a boat. This saved parts of the neat castle, but also a group of "The Forty" tribe from the great flood (frame 3037).
Her last name has been confirmed not to be Mort. This must never be mentioned again.
It had been speculated that LaPetite is actually BlitzGirl, but this has now been proved not to be the case.
