When you have to get the boat downstream, kill off the two Sintrek, the Grenadak, and the other monster. Do not worry if one of your characters dies; just take out the monsters. When this is done, destroy the two stones in the river, then the bridge (completely obliterate it), then do the same for the water mill. Then, destroy the dock. Do not be in the boat when you do this. After the dock is destroyed, jump into the boat, release the controller, and an intermission sequence will start.
Do not worry if one of your characters dies; they will come back to life after you finish the episode. However, to make sure you have a nearly 100% chance of winning, get on top of the roofs when no monster is there. Once this is done, you can snipe away at your enemies. After you shoot, go all the way back to the mountain that touches the roof, but do not go down. Shield, because the monsters will shoot your building. If you are all the way back, you will not get hurt. Do not worry -- the building cannot crash and you will be fine doing this.
