Thanks for the comments! They did have fun and the last picture was NOT photoshopped or anything.
Winky is the one that usually nips at Yoda, either nipping at Yoda's ears, his tail, or his hind legs. Yoda then just defends himself, and looks mightily scary in doing so. Winky doesn't hurt Yoda when he plays this way, he just playfully bites at Yoda and wants Yoda to chase him or what not... Yoda usually just wants to chill or he's just trying to defend himself and his "space"...
Also, no Yorkies were harmed in the Winky and Yoda at the park episode.
