Please refer to a game guide next time, there always easier but heres the answer:
in 39, first aim towards the reflectors on the right, aim to hit them and bounce over to hit the rainbow balloon and the ice balloon so it causes the rainbow balloon to freeze. As it rises hit a dart so it rickashays off the frozen balloon and into the spike ballon causing the bombs to drop and pop the bloons.
very easily
You simply need to shoot the bottom pile of bloons first. The hard part here is thinking out of the box ;) If you freeze any bloons, you will fail.
how do you beat level 17 on bloons 5?
You don't
Its easy that's your answer!
you have to shoot the arrows
shoot the balloons
you dont
you cant beat level 22 it it is impossible
well what level have you gotten stuck on? Level 18
you hit all the balloons with the darts
Very carefully...
