Offense sets up in a hori formation
Defense sets up Penguin zone. Usual 3 man cup, 1 mid, 2 wings and 1 deep.
Things get interesting when the disc is swung to the sides. Cup will trap sidelines with no return pass. The previous winger, RED 6 will drop down and cover as part of the wall. The rest of the zone will compress towards the open side.
Disc is now swung back to the middle. RED 6 returns back to his wing position.
Disc moves on to the other side, similarly RED 4 will come in and provide wall cover. You notice that RED 1 is the "Rabbit" and he can afford to take away more around angle from the thrower.
