The Angry Birds Movie 2
The Snake Mother can be seen sleeping and the hatchlings mistake her for stealing the eggs but it was the wrong eggs the hatchlings carried.

During the ending, the mother saw the eggs hatch but it was the bird hatchlings. Her offspring hatched at Zoe's house and the hatchlings hid them to reveal as a surprise, as well as the snake hid the hatchlings too. She knocked on the door revealing that the hatchlings broke her bones. They were about to fight on the beach, but Zoe showed her offspring to them as well as the mother showed her siblings to them.
