The Puzzler: Planet Squarzoid

In a squarish spiral galaxy far, far away live strange square-based lifeforms known as Squaroos. 

Baby Squaroos have little red bodies, 1 squark wide. 

Squaroo toddlers have two square red legs and an oversized orange head. Pretty cute, huh? As Squaroos grow older more squares appear. In elementary school Squaroos have grown a yellow head, which they can't hold up because they have learned the 144-letter Squaroo alphabet, which makes them tired. By middle school they have grown a new green head. They are embarrassed a lot at this age so they spend all their time upside-down, hiding from others. In high school they lie on their backs dreaming, looking up at the sky with their sky-blue heads. Fully grown Squaroos stand upright because they have so much to do. They have dark blue heads and are made up seven squares. 

How many squarks wide is an adult Squaroo's big dark blue head? To find out, look at this Squaroo growth pattern and fill in the last number:

1, 1, 2, 3, 5, 8, ____?

HINT: The fact that there are 144 letters in the Squaroo alphabet is of no help in solving the puzzle.
