Trick or treat practice

I found a smaller version of the plastic pumpkin buckets for Halloween.  I thought we would practice with fruit snacks so Indy knew what to do this year. We brought his little doorway into the living room and I would tell him to knock, then I said trick or treat and gave him a snack in his pumpkin.  He did not get it!  He would take the snack out and put it in a pile next to his bucket.  We will keep working.
