Achievement "Back Door"

[Wardstone234]

For anyone stuck on this, when you get to the second key lock, there will be a walrus who occasionly pops up on the left nearest the giant gate. If you freeze that walrus, another walrus will pop up. Freeze him and two other walrus' should pop and do the same. Then just knock the boulder off the stick and you should achieve your achievement!! Also, behind the boulder is one of those colour buddies!

I feel confident the NSA has achieved this one plenty of times xD

Just wanted to put it up incase anyone got stuck like I did for a few minutes! :)

When you jump on the frozen walrus, does it take a moment for the next one to show up?

[Wardstone234]

yeah just walk the other way slightly as if you're going back the way you came and he should appear, then freeze that walrus :) Hope that helps!
