Ralf has been the Janitor at Bash Street School for as long as anyone can remember. He cleans up all kinds of messes during the day, and sometimes patrols the school at night.
Rumour has it that he used to be a student here, but there are also rumours that he's super secret agent spy working for the queen - don't believe everything you read online!
Ralf has a slightly mysterious past. The kids don't see him too much, as he works behind the scenes fixing things and cleaning up chaos. But when he does appear, you can guarantee that he has some awesome tricks to show them, or wise wisdom to share.
He stays late to lock up the school, and arrives early to open up, so nobody has seen where he lives, or what he does for frun. He gets along well with Olive and the other teachers, but generally prefers to be alone.
