When using the Circling Sharks Exotic Emote, the player character's looping animation doesn't start where it ends. Compared to other looping emotes, there is a much larger jump from the last frame to the first frame. The holographic pool, sharks, et al seem to loop just fine for the most part. They blink unsettlingly every time the player character's animation restarts, but that is a frustratingly common issue with exotic emotes: it is not particular to this one.
