[It occurs to Bunny that Grif isn't taking this remotely as seriously as he should, even as a bedside tale for children, and that makes it less funny.]

Someone has to.

[He has to think for a moment, how to get this across to an adult, and a non-believer. He has to impress some seriousness onto Grif before ribbing can be fun to get back to, only because he hasn't grasped that Grif is from a world so far removed from his that the possibility of the fantastic and child friendly being real is too absurd to even approach reality.]

Y'ever think back on yer childhood fears, the ones you don't believe are real anymore? The ones you can believe aren't real?

Yeah, you're welcome for that.
