I need to make that one grumpy guy happy, but I don't have the old woman any more, I finished her quest. I only have the main guy. I have found one of the two methods, but I'm stuck on what to do next. Is it even possible to complete this part without the old woman? Or do I need to start the game again?

EDIT: nm i figured it out. :o

For the record: mushroom and earthworm will do the job.
