Unicorn and the smelly birdy

Dominic is playing with Pia's stuffed toy unicorn.  He has it between his legs and he's jumping up and down, as if riding a horse.

Pia : (crying out) Daddy!  Dominic is playing with my unicorn!

Daddy: It's ok. You're not using it. You can share your toys.

Pia: But he's putting my unicorn between his legs.

Daddy: And?

Pia: My unicorn will get smelly!
