The Flamingo Down The Hall

We're at the age of un-reason, apparently, because here's a recent conversation from our house:

Luke: I'm scared of the flamingo down the hall.
McMoose: ...What did you say?
Luke: I'm scared of the flamingo down the hall.
McMoose: ...You're scared...of the flamingo...down the hall?
Luke: Yes.
McMoose: There's no flamingo down the hall.
Luke: Yes, there is. It's right there. I'm scared of it.

The flamingo has also appeared in our bathtub and our bedroom. Of all the ridiculous things to be scared of, what on earth am I supposed to do with an imaginary flamingo that walks around menacing my toddler?!
