"As discrete as this little room is, I'd really like to get the hell out of this zoo before I get any older." Gretta responded.
"Ok, well, you're in charge of that, what's the best way to do that?" Todd asked.
"Hmm..." Gretta growled pensively. "I've got it and we'll accomplish two things at once if you're up for it. First, there's a hinged storm drain through the exterior zoo wall just to the side of my former home and in keeping with the overall shabbiness of this place, it's rusted enough that we should be able to knock it off it's hinges pretty easily. The second is I have an idea for how I can thank you and it's going to make it a lot easier for you to get through that storm drain."
Todd was intrigued and wondered what it could be, but was also still worried about what a giant, intelligent, human-hating crocodile could do to him if it's intentions were not as nice as they seemed on the surface. Warily, he asked Gretta to continue.
"Well, seeing as I don't really have much to give being a recently liberated zoo animal and you have this amazing device, I could get back in touch with my wild roots and you could use your remote on yourself to join me. You could change yourself to be an intelligent, talking croc like me, including keeping those hands so you can change back. Then, I could show you how to live life crocodile-style as a thank you. Unless you're only into changing other things and not yourself. What do you think?"
