New Creatures
Six new creatures were introduced in this update, three neutral and three hostile.
 * Maggot - harmless critters that just hang around in the caves. So squishy.
 * Loot Bug - big fat grub full of tasty resources. Once you Pop, as they say...
 * Spitballer - a towering, sentient plant that shoots explosive spore pods at intruders.
 * Cave Vine - inquisitive polyps hanging from the ceilings.
 * Deeptora Swarm - swarms of stinging, angry insects. Destroy their hive to get rid of them.
