The Nested Green is a Basic Blooncard in Bloons Card Storm. It spawns a Nested Blue 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.
Compared to a normal Green Bloon, Nested Green has 10 less HP but has one less charge, plus the ability to spawn extra bloons. However, the one less charge and 2 delay can be a nuisance, but is mostly compensated by having huge overall HP over more turns. Notably, it has as many bloons per card as the Swarm Green Bloon.
Nested Greens have a total of 170 HP per card, which is almost twice that of a single Green Bloon for the same cost each, more if playing on Dark Castle. However, overall HP per card is still less; Green Bloon cards have 180 total HP each, and Swarm Greens have 210 total HP per card.
Nested Greens can be a threat due to its sustained offense. Even if Storm Of Arrows can one-shot Nested Greens, the resulting Nested Blues partially fulfill additional pressure combined with other bloons.
Like Nested Yellow, a lone Nested Green is weak to Dart Monkey Twins, where two or more of them will have enough time to break apart all its HP and its descendants. Instead, combine Nested Green with other bloons.
