I can only imagine that Froggy was able to shift more and more responsibilities to Sheep, including to feed the Ribbit Ribbit Gang. Otherwise it seems ridiculous that a farm mouse who is in a convent were duck feeding is a regular task for every Nun would forget to feed her own personal ducks.
Also the Ribbit Ribbit Gang forms a Union? Is Froggy paying them or what?
The picture is good and one can feel sympathy for Froggy who is clearly overwhelmed by all of this.
