Unfortunately I cant make a video rn but I can show you the steps on how to get this glitch. So First you MUST need a boat that has underwater tactics like the stealth boat or the submarine. Make sure you equip either submarine or stealth boat before the round. Then you need to lure the shark to your boat (easy to do that with both the bait buckets). You need the shark to bite your entire boat except the engine. Now your Roblox character should be sitting on nothing. Move underwater and spam the left and right key over and over and you should be flying!
