I am a backpack, therefore i don't have a gender. So please don't call me a boy or a girl. But i do prefer he/him pronouns.
Please respect my gender and pronouns, Thank you!
XOXO Dora's backpack, Goober
I dunno, that flap at the top might be vaginal. What else would motivate the backpack to keep being a backpack otherwise, especially to the point of singing about it? Backpack could be another Chairy the Chair: 
"Oooh sit on me Peewee~"
On another note, better to be agender than going full blown Nullo. That lot of smoothies are pretty depraved.
