Well, I didn't know what to expect with this! It was certainly a unique cartoon. At first, I thought this would be dialogue from an actual phone call. I don't think people would call themselves whales and elephants like this. I don't know of this classic. I'm going to feel stupid if you just made that up.
The voices were pretty good. I really do like the sketchbook paper this is put on the back of. It can be a bit distracting at times. I like how they play off of their animal selves. It's good for some jokes.
