I found two really great discords where you can visit several Treasure Islands yourself for free. You only need to link a Twitch and/or Youtube account with discord to visit ceomg's islands. Below are a few pictures of some of the treasure islands. There is also a catalog island which Ceomg made where you only can pick up a item and then you need to drop it again.
