Kids robot movie?
I remember this story very vaguely but after a bit of thinking, I think I know the story. So I'm going to describe as if this was the story but I'm not sure.
So on the planet this is set the sun has stopped moving for a long time. Everyone on the planet are robots. The main characters are a big green robot from the sun side and a little purple robot from the night side. Both of them end up being outcast for doing something (idk what) and, despite hating each other, go on a trip together to find the sun and make it move again. After a few days, they find this really big tower that holds up the rail the sun rides on. While climbing it they have this big argument and the little one falls really far to the ground and almost dies. The little one gives up and starts heading back home but because they are from the night side, the sun is really hot so they can't make it. Eventually the big one finds the little one and saves them. After a while they make it back to the tower and climb to the top and they walk on the rail to the sun and push it(almost dying cause it's really hot) till it starts moving again(The night is saved!) but the little one was only able to survive because they climbed inside the big one and then they fell to the ground from the rail. I don't remember if the big one lived but I get the feeling they didn't.
Anyway I remember loving this movie around 2016-2020. Please help me find it.
