Thanks! Yeah Ryuk is a character from an anime...an evil character, a death god. I picked it because when my boyfriend first saw a picture of him he said that he looked like a demon (because the camera flash had given him red eyes). But its supposed to be funny because the rabbit is really a very sweet rabbit and would never hurt anything. I also just liked the sound of the name. Frog is named frog because well...he leaps like a frog. No matter how high up he is he will try to leap lol.
