Lots of redlinks, I notice is a special mission where every round only spawns RED BLOONS! It has normal rounds, and the red bloons that appear are equal to the supposed RBE of that round! But there's MORE! When bloons spawn, there is a chance (equal to the number of the current round) of a red bloon to get a reddish shield and make a redlink to another bloon, making that bloon have a shield with 1 AD and 5 HP too!
