If you play Chrono Cross, on your first playthrough, don't go with kid. You will recruit Leena and poshul if you haven't given him the bone from the restaurant upper floor.
Also, if you do that, and fulfill the right requirements, you can learn a triple tech with Leena, Serge, and razzly, a fairy you can recruit if you try to save kid later on.
