Northwest TG?

Alright, I was exploring some ideas with a friend about some TG potential on Gravitty Falls. One of them was:

> An astral creture that feeds on dreams going after Dipper sleeping
> The digested dreams cause some small scale reality altering effetcs vaguely based on said dreams

>  So Dipper dreaming about older girls like Wendy, end up resulting into plenty of residents turning into teenage girls with a crush on him (ironicaly, Wendy is unafected) 

Soooo, this is an attempt to find a good design for a girl Northwest, was thinking on including other characters like Gideon, Robbie and so on... but not sure about how good the idea is. I guess it will depend of the reception here. 

Sooo, what you think?
