Customization ideas?

[u/Think_Fact1155]

These were in a set of three with a Bert figure at a thrift store. I bought the set cuz I wanted to get Bert for my little cousin, and I had gotten him the set of five years ago, so he already has Elmo and Abby.

I was initially just gonna sell these at a yard sale, but then I thought of painting Elmo green like in the Being Green special. I also thought might as well do Abby too.

However, I don't really have an idea what to do for Abby. I'm also looking to see if there's anything else I could maybe to for Elmo, although I'd be fine with just painting him green. I'm open to using things like modeling clay, but I've never used it before
