I experienced what's getting everyone riled up about this place, the fact that the darn toads stand in your way at nearly every bottlenecked point there is.Thankfully, I finished this quest in short order and not once did I get seriously stuck anywhere.
A few pointers:
1) Take your time and don't get upset and just start going off on the poor toads <grins>
2) Don't carry anything (I forgot who, but someone on this board mentioned how they were trying to water a trough and ended up getting the bucket stuck in a bottleneck point.. not sure if the trough has any importance anywhere.. and just how do you fill the bucket with water anyways? <grins>)
3) There's this one toad that follows you in a serious bottleneck point, just keep trying to push him out of the way and if you can't, walk away and let him follow you to a not spot, then try to push him out of the way again. I think what I had to do was totally push him down to the next open area.
