A bee petting zoo! Bumblebees are very cute and very fluffy. Having a petting zoo would help people get I touch with nature, and if the guests are too belligerent about it then the bees will just sting them. I think that bumblebees might also not die after stinging, and if so they’d learn how to fight humans. When the time is right you can unleash a swarm of cute fluffy bees trained in anti-human warfare. You could use them to crush any competition. If you still want more money you can become a bee-based supervillain and rob banks or something.
