From Aldi s Cuthbert to Tesco s Curly, most British supermarkets have their own version of a caterpillar cake.
The original, Marks & Spencer s Colin Cake - who turned 30 last year - has been a staple at British birthday parties for years, with similar cakes gaining in popularity in recent years.
M&S lodged an intellectual property claim with the High Court last week, arguing the similarity of Aldi s product -the £4.99 Cutherbert Cake - leads consumers to believe they are of the same standard and ride on the coat-tails of M&S reputation with the product.
But Aldi is by no means the only supermarket offering a rival caterpillar-shaped treat with all the big names selling a variation on the classic.
