I tried to get this badge. The encyclopedia shows me having visited all the streets, and I did. I also visited Wintry Place and Vicar's Peak, both through the locked doors in Groddle Heights. Is there something else I'm missing or is this a bug?
Vicar's Peak can be reached from Thornfad Layers, I thought I got all the locations in Heights but there are I believe 4 hidden locations. Some keys may be on the same map so keep those eagle eyes on the lookout.
I made it into Vicar's Peak and Wintry Place. I looked at the link for Martleby Hare, but I can't figure out how to get in. I used spinich to high jump but I couldn't stand on the ledge. Is there another way in somewhere that I have overlooked? I have wandered around GH numerous times and haven't seen it yet. Also... is Martleby the only this I am missing or is there another hidden location I have overlooked?
