Pretty much the only way to set up a few chase scenes where heavily armed soldiers, riding in dune buggies, are unable to catch five kids on rollerskates. The evil guys do finally catch Bodhi and take the little sphere to a secret base for destruction. They free Bodhi and the magical sphere frees the water, for some reason it comes gushing out of computer terminals in the base control room, that I haven't figured out yet either. Crystal balls need oxygen to survive. Never try to get fresh with some girl who is holding a shovel.
Desolate wastelands have plenty of well maintained skating paths.
Jumping a wide chasm, without a ramp, is no problem. Owls sound just like hawks. Wax museum exhibits are equipped with motion detectors. Everything can benefit from having a flashlight strapped to it, including rollerskates and dogs. The Solarbabies discussing Bodhi.
