I have the following cadenas -
Hippo $285
Elephant $185
Pelican $185
Sailboat $330
Lion (purchased on Ebay)
Some cadenas are smaller then others and some weight more. Keep that in mind - the pelican is awfully heavy I think. Most can be purchased at boutiques if you call around. The older ones like the lion are harder to find. But they are all great fun and if you buy one you'll want more.
I'm looking for the lantern cadenas so if you see it let me know; it's hard to find.
Welcome & good luck.
You can still find the hippo in stores. Sometimes the pelican too.
