Calorie-laden milkshakes containing a "remarkable" 39 teaspoons of sugar should be banned, a campaign group has said.
Toby Carvery's Unicorn Freakshake came number one on a list published by Action on Sugar of sweet milkshakes served at UK restaurants and fast food outlets.
One serving comes in at a whopping 1,280 calories - 64% of a woman's recommended daily intake of 2,000 calories.
There are 39 teaspoons of sugar in the shake, which is more than six times the recommended amount for a seven to 10-year-old, and more than four cans of Coke.
An average 25-year-old would need to jog for nearly three hours or vacuum the house for five hours to burn off the calories.
Two Five Guys freakshakes - milkshakes with assorted toppings - came in second and third with 37 and 30 teaspoons in the banana and chocolate mix-in and cherry mix-in, respectively.
Action on Sugar said the survey's findings revealed "grotesque levels of sugar and calories" as it called for a ban on all milkshakes exceeding 300 calories per serving.
The campaign group also wants every product sold in high street restaurants and fast food chains to publish obvious traffic light labelling on menus and online, with a red label for anything containing more than 11.25g sugar per 100ml.
