One interesting plot could be the goose forming an unlikely friendship with another animal in the village. For example, the goose and the cat team up to prank the villagers in a more elaborate way than the goose could do alone.
Another plot might involve the goose's adventures outside of the village it normally terrorizes. Maybe it finds a neighboring farm and has to deal with different types of animals and challenges there, like trying to steal food from a more guarded barn.
A really cool plot could be where the goose discovers a hidden part of the village that has some sort of magical element. The goose then has to figure out how to use this new discovery to its advantage while still causing chaos among the villagers.
A crossover with Minecraft would also be cool. The goose could waddle into the blocky world, disrupt the building projects of the players. It might steal their resources like diamonds or iron, and peck at the creepers just for fun.

First, decide which universe you want to crossover with. Then, think about how the goose's personality and actions would fit into that new world. For example, if it's a crossover with a fantasy world, the goose might be seen as a strange magical creature.
Maybe there's a goose that discovers a hidden shortcut on the game board. This goose then has to decide whether to share it with the other geese or keep it for an advantage in the game. The story could follow the moral dilemma and the chaos it causes among the geese and other players.
