where is my pillooooooo??

Answer 1

It's hiding behind all of those oooooo's.

Answer 2

Assuming BigBrain is right, we can make this into an engineerring problem, and apply the following filter to pillooooooo:

f(p) = p
f(i) = i
f(l) = l

f (o, first occurrence) = o
f(o, second occureence) = w
f(o, third through seventh occurrence) = blank

then

f(pillooooooo) = pillow
