Ratchet and Clank: Size Matters Easter eggs

Titanuim Bolt inside Crank.
When you just get inside Crank, you'll see a spot where there are about 4 elecrto troops, kill them first. Then slide down, to go back up there's a ladder, but behind that ladder there's a bolt, you just need to jump around, unfortantly there another bolt on the other side of the room, i don't know how to get that one yet.
So try not to get confused which one it is.
