TheROBLOXEndless Summer Cruise was a 12-hour long Twitch event. The event lasted for two days, from August 27 to August 28, 2016. The prizes were a life preserver and a captain's hat. The game had 185K+ visits. The top 3 players who played the longest on the game got 25 ROBUX.
Purchase the First Class gamepass, then go through the First Class door and obtain the item.
The event had a negative reaction. Many players thought ROBLOX copied the ship design for a Carnival Cruise and thought there will be a lawsuit. Also the second free item, the Endless Summer Life Preserver had to be obtained by one of the two gamepasses and glitches. Only 32,107 players got the item.
