The sea monsters have started to come out of the water and invade the land. You have to be the one to save the city and throw them back in and you can do this with a crane. You will have to drive and park it correctly, without crashing it, find the sea monsters, pick them up and throw them in the water as far as you can. You will have to do all this before the time runs out. As you progress in the game the levels will become more challenging. Have a blast!
