Once fed, it can either be fed again at different trought, squeezed for some fertiliser blend (#99, #100 or #101 depending on how many times it was fed before), or if it has been fully fed it will turn into Bograda Rex leaving some Potterington Blend #102 Fertiliser in its place inside of the player's backpack, at which point it returns to the Storm barn.
The "Hunt" option can be used to path the optimal route to reach next trough.
