The solution?
They came in with a roll of paper and a staple gun and covered it up!
Out of sight out of mind!
The kids all really miss the presence of Mr Fungus though, cos for many he was like an evil uncle, who always had his eye on us, so I'm going to get them to paint a mural over it. I wonder if they will considering that last week they were trying to keep as far away from it as possible...
