A video posted on TikTok on Sunday showing children riding boats through murky brown water at Trimper Rides, a well-known theme park in Ocean City, Maryland, has prompted concern online. The clip, filmed over the US holiday weekend, shows small play boats floating in dark water, with one child riding while the surrounding boats sit empty. The user captioned it sarcastically, joking that the water had not been changed since 1999, and the footage quickly drew reactions questioning the attraction's cleanliness and upkeep.

It remains unclear what caused the discolouration or how frequently the water is changed, and the Daily Mail says it has contacted Trimper Rides for comment. Commenters variously described the water as looking "radioactive" or as though it came "straight outta the toilet", while others compared it to the chocolate river from Willy Wonka and the Chocolate Factory. Several users noted the water had appeared clear in the past, sharing older images, and an image posted by the park itself around six weeks earlier showed a child on the ride in clean blue water.
