Rubber duckie, you're the one

So I've been taking a lot of epsom salt baths for pain management, and the other day I thought...why not bath toys? They're lots of fun! My partner is convinced that this will spawn lots of stuff in the house we don't need/use, but I told her (1) I will use them; (2) if they get gross and moldy I will get rid of them/replace them; (3) if I stop using them we can get rid of them.

Now the question is...where's the best place to get kick ass bath toys? Preferably more interesting than rubber duckies. Like maybe battle ships or something? Sharks? Wind up scuba divers?
