Fry is independent soul, he likes to get into whatever you are doing.  He loves the shower.  He'll hang in there with you, come out completely soaked.

 Dr.Zoidberg is hilarious, he has this tail that tells all.  When he's going to be naughty it whips back and forth.  He is the most playful, he also demands to sleep under the blanket.  No particular place, he tends to travel and then find a spot.
