There were these two movies I watched in preschool, both animated, and I've spent my whole life, no joke, trying to figure out what they were. They would have been made in the early 90s, possibly the late 80s. The first one started with some kind of unicorns, and one that had a fake horn and the others made fun of it? The other thing I have always associated with this movie is a brother and sister fighting, some kind of fortress, and an army of blue robots, possibly pink robots fighting for the sister. They might be different movies, I don't know.
The other movie involved a hen, a hen house, and a snake trying to get the eggs? I once tried to describe it to my mother and she said it was Rikki-Tikki-Tavi but I rented it and that's not it. Can anyone help me figure out what one or more of these movies are called?? :confused:

I just remembered a bit: there were 3other unicorns, they were very small. So the fake unicorn was walking down a road? And the other unicorns pulled off its fake horn and maybe pushed it down a hill or something. And they definitely mocked it.

And the robots were blue and very blocky looking. There is an aerial view of a whole bunch of them.
