Monkey Downgrades are only accessible by bloons with the capability of downgrading your towers. Each restore costs a certain amount of cash. Each monkey can only be downgraded 4 times. Downgrades are displayed by a red square on one of these upgrade spaces. Note that all restore costs that are displayed are the Medium Difficulty costs. Unlike upgrades, the path doesn't close when a 3rd teir downgrade is reached.
