Travelers onboard cruise ships around the world are taking a new approach to souvenirs by bringing — and leaving — rubber ducks around boats.
The trend has people purchasing rubber ducks and hiding them in spots around cruise ships. Over the last year alone, TikTok videos garnering thousands of views show users hiding and finding ducks like it's a game.
In one Facebook group, named "Cruising Ducks," which has more than 284,000 members, the trend is described as a "cute and entertaining way to have a blast on cruises and to brighten others' days."

Reports say that a young girl named Abby Davis started the Easter-egg-like idea — and it has since taken off.
The Facebook group explains, "Our goal is to see how far our ducks will travel and where their journey might take them. Keep or hide, you decide, but please post your ducks' travels here so everyone can enjoy."
Members are then asked to post a photo of their rubber duck onboard a ship and to specify which cruise line they are on.

The trend has made its way to Reddit as well, with one traveler posting on the "r/royalcaribbean" subreddit, saying they paid for a carry on just for their rubber duckies.
Reddit users took to the comments to weigh in on the offbeat trend, with one person writing, "I hate to be a killjoy, but there’s really no reason for it. Just go on the cruise and enjoy what’s already there."
Another user explained that hiding and finding ducks on the ship was a fun activity for their kids on sea days when the boat didn’t stop at ports.
