Pizzicato works well for giving a kind of sneaky mood, like the generic sneaky music from Looney Tunes.
Flute and piccolo can also give an air of lively naughtiness.
On the louder side, syncopated bass can give a roving devil-may-care feeling.
I would recommend listening to soundtracks for cartoons or more kid-oriented games like Banjo-Kazooie for more ideas.
