Flying Dreadnought/Mothership/Battleship

----------

[Inevitability]

Once per round, a random object within 20 feet of a ravid animates as though by the spell animate objects (caster level 20th). These objects defend the ravid to the best of their ability, but the ravid isn’t intelligent enough to employ elaborate tactics with them.

Note the bolded part. How are you ensuring that the ship gets at least one animation every two minutes if the effect is completely random?

Note: Phoenix Cloak alone costs 50,000 gp;
Cottage-sized Flying Stronghold (10 miles/hour) costs only 40,000 (sans the base building cost)
