The Rad Bloon is a Large Blooncard in Bloons Card Storm, introduced in version 3.0. It is created by Zee Jay's Rad Bloon Time! ability and is not normally part of a deck. It allows Zee Jay's Passive Awesomeness to trigger an extra time per round while in play, though it also triggers the extra use of Passive Awesomeness on itself for the turn it is played on. This effect stacks if multiple Rad Bloons are in play. When played with Rad Bloon Time!, this Bloon's health will be 70 times the number of Rad Tokens removed upon using the ability, though if returned to the hand with Return to Sender, it reverts to having 70 health.
Although this card displays the icon for Basic Bloons, it is considered a Large Bloon and is affected by cards like Sticky Bomb and Crippling Sniper.
If the opponent lacks Sticky Bomb or any Bloon removal card, a buffed Rad Bloon is a significant threat for the opponent, especially in the early-game. Not only it can have massive HP, the extra Passive Awesomeness can be used to boost more bloons.
Return to Sender removes any HP gains obtained via Zee Jay's major ability. If the opponent removes the Rad Bloon, re-playing the card is still worth the Gold cost when planning ahead for next turns.
