I admit I'm kind of getting tired of that same music. I want there to be more sounds. Anyway, look under the car for the key. Use the key to unlock the car's trunk. Take the tire. The code for the box is "123" (sigh) and take the pocket knife.
Go over to the river. Use the pocket knife to cut through the grass on the left side and get an empty bottle. Use the bottle to catch the lightning bug back at the car. The code for the electric box is Star, Square, Triangle, Star, Circle. Look up the walkthrough for the rest.
