The best and ONLY tolerable episode in the "Legends of Bikini Bottom" trilogy. Objects and certain characters going missing is an interesting addition to the episode, and I liked the mermaids. They were cute and funny, and Patrick falling in love with them was funny, too, and made a magnificant callback to the movie. The ending where all the mermaids had to do was sing their song backwards to escape the triangle seemed rushed for me, but at least the rest of the episode flowed smoothly, and wasn't too forced, and went by too fast. This is the only great episode from "Legends of Bikini Bottom". 8/10
