Increase Power-Up Duration Upgrade: It can increase the duration of the power ups that are active.
 * Valuable Mowers Upgrade: It is an upgrade that can make the lawnmowers give two coins instead of one. It is found in the files.
 * Description: Drops more money for each lawnmower at the end of a level.
 * Change Vase Color Power-Up: It is a powerup that lets you change the color of one vase, for example turning a brown vase into a green vase.
 * Barricades: Back in the 1.4 version, there were environment modifiers that could move zombies either up or down a lane. They were found in the old Dark Ages Brain Buster. The types of barricades that existed were: barricade_up, barricade_down, barricade_up_noncolliding and barricade_down_noncolliding. Regular barricades did not let you plant in them and non-colliding barricades leave you plant above them. These are used in the Chinese Brain Buster called Fright Night Theatre, which was going to be in the international version but went scrapped.
 * Endless Mini-games are endless versions of Mummy Memory, Cannons Away and Not OK Corral.
 * what about the unused farm world?
