For anyone looking for tips and tricks on how to get cleany to clip you out of bounds(mainly for you MIX UP GAMERS), I have a few methods that might work(they worked for me at least).
1. Try to get cleany to push you against a corner. The corner that seemed to work for me the most was the corner of the hallway right next to the room with the picture of the drep dog.
2. Let cleany carry you for a while. There will be a slight chance that cleany will get stuck somewhere with you and clip you out of bounds.
3. If cleany is stuck somewhere, try to maneuver your way through him and he should push you against the wall.
