I added some popular Vtubers to my island, maybe you could do the same The ones I added were Dokibird, Mint Fantôme, and Nerissa Ravencroft.

I added some musicians, you coould add Michel Jackson and Beyonce

If you want you could add political figures, that might make your island pretty interesting. I did that myself - it's how my friend ended up being best friends with Obama and how Donald Trump ended up married to Kamala Harris.

add Big Boss or George Costanza
