Big Verticulral Aeaarial Faith Plate
Basically, you throw a shell from the right, it gets launched on the blue eye thing. If you do it to the left, the shells throwed by the small aerial faith plate will touch an healingstation and will heal the plate by 1hp.
It has 20hp, and turns into phase 2 when it has 10hp.
