Bloons TD 6 is 5 years old!!! That only means one thing: Time for a birthday party! The Bloons are only here to party, so don't worry about losing lives. Your goal is to pop the Party BAD as many times as you can. You're on a special track called Circular where Bloons circle around and don't leave 'til they're popped! Have fun! Also ALL the Monkeys are here, even the Bloonchipper from BTD5!
