A: Yes, you have to show them to everyone as you draw them. That’s to keep players honest – otherwise you could just draw a bunch of cards and keep them, without the accountability of having to stop when you get to a Keeper or Creeper.
So you’d flip those face up into a pile until you decide to stop and take the pile into your hand… or until you draw a Keeper or Creeper, in which case you’d play that in front of you, and put the pile of previously drawn cards into the discard.
