Before starting the cleaning process, let's combine all the levels together.

1. Click on `File > Open` and open the .pomf file for level 1 (01 - Entry Level.pomf).<br>

2. Use `File > Save As` to save it as a new Pollination model. Let's name it Full Model.pomf.<br>

3. Use `File > Open` to open the new model (Full Model.pomf).
4. Now use `File > Import` to import `02 - Floor.pomf` and `03 - Floor.pomf` into the full model file.<br>

You may need to turn on the visibility of the level after importing them if the visibility is off by default.
