You need to get the car up in the ferry, but the problem is that there are water all over the place and your car will just fell off if you just rush in. You need to build a bridge so that your car can run on it and get aboard the ferry clean and dry.
You need to figure out how you can get aboard the ferry. Sure, it would involve dropping some boxes and anything that will float in the ocean, but you need to figure out how it should be done. It you don’t get it right then your car will fell in the ocean and you will drown.
