leviathans don't like your base, and protection measures

this is a hand in hand feature. noa mentioned growing creatures from the egg to protect your base. but they dont really have a reason to protect. so leviathins like the collector or others when added could occassionally attack the base when your in it. be it tearing off pieces and flooding it an dhavign unique interactions if your in the torn off chunk, or just messing with durability, they attack. and your tamed creatures can fight them off!
