As the credits roll, the Solarbabies are swimming in the surf. There is a cut to Darstar standing on a rock, taking off his shirt and diving in to the water. In the cut, all 7 of them are splashing in a circle and there are no rocks anywhere near them.
How did "Greentree" and his people get that map to the Aqua Bunker? And, since he clearly doesn't have plans to storm the Bunker (as opposed to the Solarbabies), why would Greentree keep something he had no intention of ever using?
Why does "Gavial" just vanish from the movie, following the RED ALERT/EVACUATE signal at the Aqua Bunker? The picture seems to suggest that he escapes, but this is never substantiated; Gavial simply flees the control room and never reappears.
