If you're feeling, "Why can't I get this stupid creature to MOVE?!"
This article's for you!
Each of these "blocker" animals has a designated path, walking from point A to point B.
If you disrupt this path, by turning or rotating a block along this path, the blocker animal will go to the remaining point it can reach. The animal will stop moving, until you reopen its path.
Other blocker animals, like Storks and Frogs can be frustrating too!
Storks are stationary animal blockers and can't be moved. Simply rotate them away and use a different path on the block.
Frogs, while appearing to block the player's path, will always hop away once the player walks up to it.
