Ben 10 Power Splash
You are a boy with super powers which let you transform into amazing creatures. This time some bad guys are running away with a hostage in a boat. You need to persecute the bad guys and free the hostage. To accomplish this, you initially transform into a sea creature and swim under water. At this level you have to avoid all of creatures and objects, but powerups. If you survive this stage, you transform into an insect. As an insect you have to fly above the boat, shoot the bad guys with green balls and avoid the grenades they throw to you.
