MO-J4

MO-J4 is the Bot-Bot assigned to the Star Darlings.

Character
Bot-Bot guides roam the campus to direct students to classes and just be generally helpful. But MO-J4 isn't an ordinary robot. When he led Sage on her campus tour, something sparked inside him. Quite unexpectedly, he formed an attachment to Sage and wanted to help her however he could. Sage is star-stoked about that. He makes her laugh and has a heart of gold!

In the show, MO-J4 is the Bot-Bot assigned to the Star Darlings. In the books, the Star Darlings sometimes refer to him by the nickname "Mojo."
