I walked into Bears' playroom to find this. The vent cover was moved aside and there was at least, a dozen little people toys right around the vent. I cleared them away so I didn't knock them in making it even worse.
There were two that landed within reach. After getting those out, I then held my phone in the air vent and took a picture to see if there was anything else. I wasn't sure where the vent even went to so the picture helped. It was slightly tilted downward and I just hope that he didn't throw anything else down there like a ball.
There is no way to know for sure, but I think the Little people toys just got knocked down there rather than thrown in. It took a pair of tongs and my arm wedged in as deep as I could to get it back.
The bunny is safely back in the mix of toys after a Clorox bath.
