Walrus 1: If you get the bends, it can be quite narcotic, you can get a kind of narcotic effect. You don't know which direction you're going in, you don't know which is up or down, you don't know how long you've been in the water, you can't regulate yourself anymore. I think it's really, really dangerous.
Walrus 2: I've had altitude sickness which is like the opposite, isn't it?
The Shark: Er, I just don't really like the idea of feeling like eating fish, which is a bit dumb 'cause obviously they're there, erm, the bit that I really hate is when you get, erm, all that like, seaweed, yeah, I suppose it is seaweed, that kind of like catches round, you know, that brown stuff like, erm, tagliatelle, but it's, erm, that kind of like wraps itself round, that's when I get a bit freaked out and I kind of think I'd rather be in a swimming pool.
The Shark: I have to say I don't really like the idea of what's below. I find it a bit kind of like, ooh, I think how deep am I, or is there going to be kind of, you know, 'cause I do swim quite a way out but I have to say the further out, it's sort of like testing myself, like 'go on, go on, how far can you go'.
The Amoeba: I think I have a very intimate relationship with water 'cause I'm primarily composed of it. But I do think water is one of the great mysteries.
