It turns out that octopus tentacles still react up to an hour after being severed from their bodies. Frog legs have a similar effect if salt is put on them. I could handle the fact that the tentacles were moving since I knew that they were not alive, but the texture was a little too much for me. I tried one tentacle and I was done. My friend, on the other hand, ate the whole plate. Day 2 on Jeju Island was when the real adventure began. Since Jeju is notorious for its beautiful waterfalls and beaches, we had to have a look. We took a bus to the south part of the island, about an hour from where our hotel was, and saw Jeongbang Falls first.
