5. Return of the Wispa Bar
Following Cadbury's ill advised plan to rebrand their most popular products, for example the Cadbury's Caramel became Cadbury's Dairy Milk with Caramel – a mouthful of the wrong kind leaving the Wispa with the dull title of Dairy Milk Bubbly.
The beloved chocolate bar quickly died out but soon enough the pleas for its reinstatement resonated from whispers to shouts. Fans campaigned for its return forcing Cadbury to perform a test run with an amazing 20,000,000 Wispas selling within seven weeks!
