I vaguely remember a show about a pair of robots. One was pink and one was yellow, I believe and I recall them being brother and sister. They were only about waist or knee high. I remember the beginning of the show started with them hiding behind a bush until a human walked by so they wouldn't be seen. Then they saw a garage door go up nearby and hide in there for a while. When someone found them, the yellow one's glasses started glowing a bright whitish/blue color. I think the robots lost their energy because there wasn't enough love in the world. I think they had hearts on their bellies and special capsules that looked like glass bubbles that the recharged in. They were not fighting robots. Any ideas would be greatly appreciated.
