Use your FLUDD backpack to escape from the evil creatures. Assemble the pipe, and then keep poisoning the plant with weed killer until it dies. Then you will be able to use it to get to the next level. This game is very similar to the concept of Super Mario Sunshine (for the GameCube). It's really fun flying around with your water-powered jetpack and killing the flying fish, turtles, ghosts, and more. Everyone should give this game a try, it's very fun.
