Boolean is a Bat Plushie who shows up in Di'angelo: Stuffie Scouts! and Di'angelo.
She along with Lucas and an unnamed ZomBear find shelter in the Stuffie Scouts headquarters.

She tends to complain about her small wings, saying how using them is pointless, because they're utterly useless. However, she makes up for with her incredible speed when running (but she's not as fast as Di'angelo!). In an ironic twist, she actually make use of her wings later. XD

Boolean's design is quite ambiguous, and I like it. XD
At first glance, you assume she's a boy, because of the lack of eyelashes I make mandatory on all my females today.
Her name also doesn't help. XD
I remember I did that, because I didn't know what gender to make her at first and when drawing her, I was leaning towards boy at the time, but later changed her to a girl because... I don't even remember. XD
