When Roz first tries teaching the gosling to fly, she launches him high into the sky, where a flying bird swoops over and grabs him in midair. Immediately after, Roz has him back in her hand, even though the bird should have him.
When the fox enters the lodge, a moose near the doorway grunts but the sound effect used is a recording of a bear.
At 43:12, Roz can be seen touching the projection on the cave wall with her hand and casting a shadow onto it. However, the object (also with its own shadow) creating the projection is in her other hand. So, not only should it not have had its shadow, but it should have been placed on top of a rock or something so that the projection would remain still and Roz' shadow would be visible.
When Roz activates "learning mode" to learn the animals language, she pulls out a tablet and presses some buttons to do it. It wouldn't make much sense for a robot to have to pull out a device and enter inputs to perform a certain task, instead of just doing the task by itself.
