You chop down 6 iron acorns.

I spent about 90 minutes looking for oak logs. I found one, damaged one, but I got about five dozen iron acorns [no wonder the game is populated with squirrels], and enough swan feathers to make Bjork envious.

I know my character is often mentally challenged, but sometimes I even think he can decide whether to pick up an iron acorn or a swan feather and not mistake it for an oak log.

It's amazing to think of how many swans inhabit the oak trees, but getting oak logs from an oak tree is nearly impossible.

This 90 minutes made me feel like I was wasting my time, and while I somewhat expect someone to go [if anyone even looks at this thread] "you're not entitled to receiving an oak log", it's a TREE. Getting a log should not be this stupid.
