SORRY I keep drawing blank. look at the list of walkarounds and parade, maybe you could adapt some of those. A change bag in which you put in some small toy trash ie barie soda can etc and bring out some thing on the other side to show recyling, can you do christian based, song He's got the whole World in His hands. and "Pa pa can you hear me" is a beautiful song about earth and how we treat it, not for a clown but a puppet could sing. A feather duster as a prop to clean up you shoe, remove troubles and frowns etc.
I mean to clean up your show as in clean act.
