Hi Bob,
I know this is very late but I'm trying to catch up on a few of your past levels.
This one has had me stumped for a week or so. I just couldn't get the combination with the right hand side, but finally Stinky managed to get to the left hand side this morning! Then I discovered that he couldn't exit because the flame hadn't been extinguished.

Back to the drawing board again.
After about another 10 tries the we all got home together!
Quite a challenge for me. Thanks for the fun Bob
