I want a bumbus.... but have no idea how to get one. Don't I have to have the random event of being visited by the queen bee???

If you want to create a new Bumbus, you can adopt one at any time in the Blue Building c: The RE and quest from Queen Bea will turn an existing pet into a Bumbus

First, you need to be able to get into the Blue Building. There, you can either adopt a Bumbus or have the Queen transform one of your existing pets into a Bumbus. You do need to get the random event to unlock the Queen option, though.

OH yes the blue building! Thanks both of you!
