There are _six_ different Clockwork Tunnels.

Red: Inferno Passage
Green: Overgrown Path
Purple: Haunted Passage
Yellow: Hall of the Wild
Blue: Hall of Goo
Blue: Mechanized Mile

Both Hall of Goo (seen in Firefly) and Mechanized Mile (seen in a few arcade gates currently) have what looks to me as identical icons.

Q: Has anyone seen Hall of Goo, or Hall of the Wild, in gates in the arcade? If so, do you know what color the totem pole had for that level?

Q: Has anyone seen any other Clockwork Tunnels? Are there duplicate for the other 4 icon colors as well?
