How to assist a child in getting adopted:
1. Assess situation and develop plan.
2. Call upon slave robot clone to take your place while you implement plan.
3. Use superpowers to fool potential parent(s) into believing child is worth their time and money.
4. Repeat until goal is achieved.
5. Return slave robot clone to hollow tree until next time.
Supergirl treats that robot as badly as Superman treats Supergirl. That robot probably has a rock or something inside that tree that it likes to boss around.
