Watch ground move
Go to practice mode and select either of the lodge levels. Choose a deep or bottom lure (lizards recommended). Cast it by a launching dock and reel it in quickly. Jerk the line to the left you should see the ground move. This also works for either of the reed levels. Cast out by a stump surrounded by lily pads. Use a deep or bottom lure. sink it to the bottom then reel it fast and jerk the line to the left.
