How do you spoil roly-polys and what does pregnancy smell like?

Buzz and Zanzi were fighting over who got to keep the roly-poly in their room.

Mama: Why don't we just bring roly-poly out here and I'll babysit the roly-poly for a while.
Buzz:  NO!  You're a bad babysitter!  You'll spoil him!!
Mama:  How am I going to spoil him?
Buzz:  Why don't we just leave him out in the living room to make it smell better?  I don't like the smell of pregnancy.
