The Monkey Tower is a tower that, ironically, is not a monkey. It can, however, contain up to four monkeys. It is based off the "standard" tower defense towers that are actually towers. Not all monkeys have to be the same, but there is a bonus for each group if they are. This will be covered later on. This tower costs $1050. Note that clicking this opens up a mini-menu that lets you upgrade the towers inside.
