Once a classic '90s candy that satisfied many, Butterfinger BB's were dropped from Nestlé's line of confections back in 2006, and there's controversy as to why.
One theory is that the chocolate’s quick melting point determined the candy's fate. The chocolate seemed to slip off the candy more quickly than it could reach your mouth.
In 2009, Butterfinger Bites were released in an attempt to copy the iconic BB’s, according to Insider. The bites were well-accepted, but they couldn't replace the poppable version.
