We keep a hamster wheel with a toy hamster in it - started in our 2013 S and it continues with the 2018 S replacement. Always good for a laugh when we show off the 'engine'.
I have a model GM V-8 I got on Ebay up there. It's visible between the two cats in my avatar. I often forget the frunk is there though.
The frunk is great for transporting food- it keeps the lingering smells out of the car.
Biodefense mode for 30 seconds is usually good for this too.

I had to refiill two propane tanks at once a year or so back. I removed the cover to the smuggler's hold in the back and put them in there. The guy who filled the tanks at the local station had a lot of questions about the car. He had actually driven my car across the parking lot when I got a piece of metal in a tire on a holiday weekend and had the car towed to their shop. He was impressed with just that short drive.
