Why do bps sit in weird positions? is it to stretch? To get a better view?

I went into the snake room and Yzma was half out of her hut. The next second, the half that was out was doing a back bend over the hut and she just sat there, resting on the hut draped upside down. I could not stop laughing!!! Didn't have my phone to get a pic. I did pick her up and listen for wheezing incase she was trying to breathe, but it was silent. she was just being a goof.
