Not much is known about Chu, but that doesn't mean there isn't stuff to say. He is an eel alien created by DA user TitaniumToenail. All he wants to do is chill out, eat out and make out with anyone if they're nice to him. 

You saw him try to get some food, but watched as he had to walk away due to not having enough money. You decided to be nice and buy him a burger and fries. After you two ate together, he was ready to thank you for doing that for him. In his own special way...
