[X] Some Blamps become darker in color, allowing them to absorb more light. This allows the Blamps to grow faster and reach a larger maximum size, as well as acquiring a thicker skin. This both makes it harder for vent Blamps to disrupt them and harder for Drekin or Harpoon Slina to break their skin. To encourage the spread of their much heavier shelled buds they are wrapped in fruiting bodies.
My variation of the heavier Blamp plan.
