The bloons and monkeys have raged an endless war for centuries. The monkeys are training endlessly but they still don't seem to be strong enough to stop the bloons. Especially since the bloons are getting stronger. But there's still hope. With the legend of upgrading, the monkeys believe that by training as hard as possible, they'll upgrade and become more powerful. The king doesn't believe it, though. He ensures that the monkeys train normally. But throughout all the types, they're hopeful. The bloons are getting stronger and the monkeys need to hurry if they want to beat them. And the bloons are going all out, to the point of creating stronger bloons at the expense of others. And these ones will take all the monkeys' power to destroy. <==={[
