Yeah, I have my own convoluted theory (or two) about the Girl Stinky/Grandpa Stinky/Sal debacle. One of which involves both Sal and Stinky being tar golems created from another undiscovered Toy of Power, and giving the Narrator a larger role in the story overall. Another involves Grandpa Stinky being Neptune, the God of the Sea, and Girl Stinky being a sort of surrogate granddaughter, but still made from fish, coffee, tar, and a rib.
