George Weasley: "How big did his tongue get?"
Arthur Weasley: "It was four feet long before his parents would let me shrink it."

The Ton-Tongue Toffee was a rainbow-coloured magical sweet invented by Fred and George Weasley for Weasleys' Wizard Wheezes that, with the power of the Engorgement Charm, made the tongue of the consumer swell to an indeterminate size (at least four feet long).[1][2]


"Dudley was no longer standing behind his parents. He was kneeling beside the coffee table, and he was gagging and sputtering on a foot-long, purple, slimy thing that was protruding from his mouth. One bewildered second later, Harry realised that the foot-long thing was Dudley’s tongue — and that a brightly coloured toffee wrapper lay on the floor before him."

A Ton-Tongue Toffee sweet

In August 1994, when the Weasley family visited 4 Privet Drive to pick up Harry Potter to go to the 1994 Quidditch World Cup, Fred Weasley "accidentally" dropped one of these toffees on the floor near Dudley Dursley which Dudley then picked up and ate. Fred was aware of Dudley's bullying, through Harry's letters to his brother, Ron Weasley. He decided to use the toffee to get back at Dudley, knowing that the temptation would be too great for the greedy boy to resist; especially because he also knew that Dudley was currently on a strict diet set by his school nurse.[3]

The jinxed sweet caused Dudley's tongue to quickly swell, making it look like "a great slimy python" and almost suffocating him. Uncle Vernon was so outraged at this that he flung several pieces of china at Arthur Weasley, while Aunt Petunia attempted to pull the object from Dudley's mouth, not realiseing what it was.

Arthur ordered his sons, and Harry, to depart through the Floo Network and eventually calmed the Dursleys down enough to let him restore Dudley's tongue. Arthur was enraged by the prank, due to his views on Muggle-baiting, though he was somewhat mollified when the boys told him of Dudley's bullying nature, and that that had been the motivation.[1]

The twins tried to sneak some toffees into the Quidditch World Cup, but were caught by their mother's Summoning Charm.[2]
