walking to get her tired isn't good for her. Short walks only to learn proper walking technique. Shes not fully vaccinated either so more reason to avoid lots of walking. Play time with toys is what will be best for her energy. We want to reduce repetitive exercises on cement, flat surfaces and stairs while she is growing.
As for the toy, not to sure, my girl will play with anything. shes got balls and ropes all over, antler bones, but her favorite toys are cardboard papertowel rolls, empty plastic milk jugs and unfortunately shoes.
