Singapore speedcuber Calen Seah sets Mr. Potato Head assembly record

Calen Seah did not need a cube to show what speedcubing hands can do. The Singapore teenager turned that same finger speed and sequencing discipline into a Guinness World Record, assembling a Mr. Potato Head in 4.63 seconds.

The record attempt took place in Singapore on January 3, 2026, when Seah was 15. Guinness later published the story when he was 16, and the time was measured to the nearest 100th of a second. For a toy first released in 1952, the challenge is not just a sprint. It is a test of dexterity, order, and nerve, the same ingredients that decide whether a cuber locks in a clean solve or flubs the last move under pressure.

Seah’s path to the title looked much more like a training block than a one-off stunt. He said he had watched Guinness World Records videos as a child before he began speedcubing on YouTube, and he believed his Rubik’s Cube background would translate if he practiced enough. The project started in late 2023, when he asked a friend to buy him the toy for Christmas so he could begin. His practice went quiet for a while, then resumed in mid-2025. Guinness says he likely assembled the toy around 400 times in training, and the record came on about his 20th attempt of the day. The first official try was disqualified, but Seah stayed with it and eventually converted the effort into the recognized mark.

That makes the record feel closer to a cubing result than a novelty headline. Seah’s World Cube Association profile lists 24 competitions completed and 833 official solves, with personal records of 6.53 seconds in 3x3x3 cube single and 11.53 seconds in 3x3x3 one-handed single, plus results in clock, megaminx, pyraminx, skewb and square-1. Those numbers point to a solver who has spent years learning how to move quickly without wasting motion, how to plan ahead, and how to stay composed when a timer is live.

The Mr. Potato Head title itself has been moving recently. Declan McFerran of County Antrim, Northern Ireland, set the previous mark at 5.15 seconds in June 2024, after Guinness said Matilda Walden revived the record in 2021 with a 5.69-second time. McFerran’s split-second approach showed how specific the build can get, with simultaneous motions and a non-dominant hand used for part of the assembly. Seah’s 4.63-second run pushed that benchmark lower and showed the same lesson cubers already know: fast hands matter, but so does the order behind them.
