History:
Once a team of Engineer Monkeys found the broken pieces of a Delorean near some train tracks. They reassembled it and recognized it as a time machine. They planned to show it at the opening night of a new Monkey City. But one night, a curious Dart Monkey snuck into the garage and got in the car. What the Engineer Monkeys didn't know is that when fixing it, the time machine turned sentient. The Dart Monkey accidentally fused with it and they became the Time Travel Tower and since then, they have been using their powers to pop bloons.

Trivia:

 * Back to the Future reference. Obviously.
 * Type 'Time' on a phone to get the price of the Time Travel ability.
 * The curious Dart Monkey in the history section was not intended in any way to relate to the kids TV show Curious George.
