A very human one.

They shared a very happily quiet companionable moment together until suddenly!

*Loud growling gurgling stomach sound*

Walt flushed with embarrassment. "Sorry about that. I have super hightened metabolism and it chooses the most embarrassing times to make itself kno-"

*Even longer and louder and more desperate growling gurgling stomach sounds*

Penny turned bright red. "I sometimes forget that this body is the kind that needs nourishment for sustained activity now until the embarrassing sound happens."

Walt chuckled,"I think we should both get something to eat then." Spying a convenient turn off point from the Hyper Highway!!!??¿¿¡¡¡☆* (trademarked and copywrited but patent pending lol) they pulled onto a long strip of fast food and gimmicky theme restaurants. "You probably have still only had limited experience with food. Tell me if you see something that you'd like to try and we'll stop and give it a go."

Penny's eyes grew wide with amazement. "You mean that you'll allow me the honor of choosing where and what we shall dine upon, friend Walt!"

Sensing he might have made a error in judgement but not willing to go back upon his word he nodded but solemnly told Penny. "Indeed. But you have to choose one. We'll try others another time but today it's one location."

"Understood! Don't worry friend, Walt. I'm feasting ready!"

Walt groaned as his bad feeling about this escalated. As Penny hungrily eyed...

Tomboy Outback

Goth Ihop

Milf Dennys

Super Hero Hideaway (just as they are changing over from family friendly to naughty nightclub of course)

The Cats Meow -a catgirl character themed restaurant

Princess Palace - a Princess character themed restaurant

A Magic Ale House/ A Magic Brew- a witch and wizard theme

RWBY Thursdays- A RWBY themed knock of the Ruby Tuesdays chain serving the expected burgers, shakes and fries... but also cookies, pancakes and tuna thanks to Ruby, Nora, Blake and their fans.

(Any suggestions folks?)
