What stocks are you curious about but too afraid to invest in?

I'm starting a new series where my dog chooses between two investments, and whichever one he picks, I put $10 into it. The series only works if people comment ideas for what he should choose from next, so I’m looking for more investment options to include. What stocks, ETFs, or investments have you always been curious about, but have been too afraid to actually put money into? This is just for fun and entertainment, not financial advice.
