Recent bedtime conversation with my oldest:
ME: Yes, honey?
LILY: I want 'too-loo.
ME: Who do you want, honey?
ME: Oh! You mean Cthulhu? *
LILY: Yeah! Ca-too-loo!
ME: I don't know where Cthulhu is right now, honey.
LILY: Maybe he's lost!
ME: Oh no, sweetheart. Cthulhu isn't lost... he's sleeping.
* What? You don't have a stuffed Cthulhu?
