If you're still good with it, Yondu's got a few science folks in on the build-a-fence project around a couple of communities (Bulma, Devero, and Kaiba were definite yesses and anyone else who pings in on that or joins them). A couple of areas have deep ditches and spike traps (courtesy Vegeta's help) to deal with void blobs and there's a few cowtraps (Sonya Blade's idea) to deal with the giant goats. He also bounced the idea of sandbag alcoves to avoid the Dralites off Elidibus, at least until the baby situation is taken care of. He fully credits Amaya for having discussed that before.
