You can buy it on Amazon. The bear is using the shark as a surfboard. That is an ankle strap, not a chain.
This one replaced one with a bear, holding a rifle, riding a shark. This one, actually. Only we paid $15 for it. Looks like the price went up.
Our next shower curtain won't have fire arms in it. Insanity of some kind, but no fire arms.
You can buy it on Amazon without the wiener. OP, what's up with the wiener?
Edit: There is another version that has the rocket wiener. I think it's supposed to be a cigar?
