Upgradeatron

The Upgradeatron is a bizarre tower with a crudload of upgrades. Not all of them make sense. It costs $1337 on medium. It resembles a Dart Monkey, but it glows orange and phases between normal and completely invisible. It has 137 health, and pops 7 layers off of bloons, 13 to MOAB-class bloons. Note that third-tier upgrades and beyond are not mutually exclusive with this tower. Oh, and it launches ordinary darts.
