Anybody else's kid make up strange games?

[LeftyMom]

LeftyKid made up a game a while back where he'll cup his hands like he's holding something and bring it to me. He tells me what it is, then I tell him thank you and take the invisible object from his hands. It started out with simple things like toys, then he started bringing me imaginary animals (sometimes he tells me that they have owies and need help) or cartoon people. Then it got really weird and he started bringing me things like planets and prehistoric animals.

In the past few minutes he's pretended to bring me my keys (I lose them a lot,) some money, a flowerhat jelly, an anomolocaris and Swiper from Dora the Explorer.

Is my kid wierd or do your kids do stuff like this too?
