for some reason i cant find out where to go i turned into the dark prince and i made it to what looks like a door that needs to be opened by some sort of switch but i cant find the switch is there some sort of trick i need to do i tried looking every where in the tunnel and i cant figure it out
when you get to that part, slide all the way down of the ladder. you'll find a block switch. pull it with the daggertail and the door will open. get to the door as fast as you can ( use slow-mo if you want to ) and you'll come to an area with a wall chain run and ledges and beams, get to the top and the door will be open. go through it and get into the water pool. everything is pretty straight-forward from here.
