Cuthbert is a caterpillar, and also a cake. He lives on the shelves of Aldi in the bakery aisle. He happens to look a lot like another caterpillar called Colin. Colin is also a cake. He lives on the slightly more refined shelves of Marks and Spencers' bakery aisle. As Colin enjoys what might be perceived as more luxurious residence, his presence at birthday parties has a higher price tag.
Marks and Spencer have alleged breach of IP and Aldi have taken to Twitter to launch their hilarious defence. And actually Marks and Spencer's social data have responded in an equally well humoured way.
Over the course of the last few days Aldi has posted a string of #freecuthbert related tweets which are capturing the public's imagination. They've also called in Caterpillar Cake cousins Cecil, Wiggles, Curly and Clyde, from Waitrose, Sainsburys, Tesco and Asda as back up.
Aldi have approached Marks and Spencer with the offer of a charity donation from the sale of every Cuthbert the Caterpillar cake, including to one of the M&S supported charities, and while M&S are open to dialogue, no one is backing down.
