Kelp
a word used to refer to a little kid - usually a naughty little kid, or mischievous wild rascal. Derived from Scottish 'Kelpie' which is a water spirit (or sprite, or imp or... you know those kinds of folklore-ey things).
They roasted their marshmallows and then the little kelps only went and tried to stick the marshmallows on Grandad's head!
