1. Fox obtains the first one from an enslaved SnowHorn he frees using the Shackle Key. The SnowHorn tells Fox she found it while she was working, and because she thought it was important, she hid it from the SharpClaw. This Bridge Cog is used on a machine on a platform by the waterline at the other end of the river a little further down the road from where Fox frees the SnowHorn. After placing the Cog, Fox has to pull a lever to make a bridge extend to the other side of the river. 3. The third Cog lies in the building the five SharpClaw came out of.
