Rain plagiarized from an otter?

Rain stated that if he gets 1^st place in Music Bank this week, he will hold a fish and do the otter dance. This promise was made on the KBS Radio show “Narsha’s Raise the Volume” recording on May 4th in response to a question asked by a listener who asked, “What’s the relationship between Love Song and an otter?” Rain replied, “On the internet, there have been allegations claiming that the choreography of “Love Song ” was plagiarized from a video of an otter doing the wave dance with a fish in its hand.” He continued by saying, “I always thought that if I win 1^stplace in a music program, I should hold a fish in my hand and do the otter dance. I didn’t have the fish ready because I didn’t expect to win last week, but if I win first again this week, I will definitely bring a fish up to the stage.”

Unfortunately, Rain didn’t win 1^st place this week, but there is always next week. So, who wants to see Rain do the otter dance with a fish in his hand?

Below is a video comparing the choreography of Rain’s ” Love Song” and the otter dance. Are they similar? Did Rain really plagiarize?
