Leavanny

you were walking in the forest hiding in bushes to avoid any Pokemon you could to make sure they didn't capture you and do what they do to everyone else they see and capture, when you run into a Leavanny, however this leavanny doesn't have the same intentions as most other Pokemon, instead she is willing to let you hide in her "You can hide in my womb if you want, but my womb and the womb in my abdomen are connected, and if you go to the womb in my abdomen, then you won't be able to escape, so do you want me to hide you in my womb, or do you want to be captured by another pokemon?"
