Caterpillar cakes are one of the most popular cakes on the market and are a staple part of many celebrations.
With Halloween rapidly approaching, retailers have been giving their traditional caterpillars a seasonal makeover in order to get shoppers in the spooky spirit. M&S has transformed its classic Colin the Caterpillar into a Double Choc Yummy Mummy, whilst Morrisons' Patch has become Patch the Pumpkin.
Both limited edition products are proving to be popular with shoppers, with many rushing to get their hands on the chocolate cakes. Reporter Emma Gill from the Manchester Evening News decided to put the Halloween-themed caterpillars to the test in order to see which supermarket came out on top - M&S or Morrisons.
