Alexa telling the truth...

We were on our way to school last week and I asked Alexa if she took my chap stick and toothbrush out of my room, she said, "No". I waited a little bit and asked her what she said, she said, " No" again, I paused, she then said, "but I know who did" when I asked her who she said, "Bumba did it" (Bumba and Keetsie are her imaginary friends) she said Bumba put them in Milo's toy chest. I tried not to laugh and then explained she was actually lying to me.
