Permanent upgrades are purchased from the Ant Builder using Cornucopias. The cost of each upgrade starts at 3 Cornucopias and increases linearly at a rate of 1 up to a maximum of 20. Once the cost reaches 20, the ant will no longer offer additional upgrades. Some upgrades are unique and others are repeatable.
Some upgrades like "Water Pigeon" seem to be named, but most upgrades do not have a name currently.
