The Nested Yellow is a Basic Blooncard in Bloons Card Storm. It spawns a Nested Green if it is destroyed, which does not inherit any modified properties of its parent (e.g. its Delay or being On Fire). It does not summon a Bloon if the player's Bloon track is full when it is popped, even though popping it opens a space.
Nested Yellows have 10 less health than normal Yellow Bloons but have only 1 charge, have 2 delay, and cost 1 more Gold. However, it stands out as a durable bloon with incredible overall HP and continuous threats of all its offspring.
At 290 overall HP, this is over twice as much as a normal Yellow.
This card has 4 total bloons per card, one more than Swarm Yellow Bloon's 3 bloons.
Nested Yellows are a major threat, especially combined with bloon swarms, providing continuous pressure to the opponent. Even if able to be one-shot by Storm Of Arrows, its Nested Green can act as a similar threat, albeit 40 less HP than the Nested Yellow.
Nested Yellow as a starting Bloon is weak to Dart Monkey Twins; two or more of them can chip away at its HP and all its offspring over many rounds. Hence, Nested Yellows should be combined with other bloons.
