As he tucked his tooth under his pillow, Felix had his hopes up. "Maybe I'll get a shiny silver dollar. That's what Benjamin got when his tooth fell out".

Fairy-wise, he's on a strict Don't Ask Don't Tell policy. He talked about what he hoped to get, but didn't even once mention the tooth fairy. It's the same with Santa Claus: he was full of questions at age 3 but by age 4 he was studiously mum.
