The Whatchamacallit brand is asking fans to name a new candy bar for a chance to win $5,000.

Launched in 1978 by The Hershey Co., it chose “Whatchamacallit” from a list of nearly 100 names. The original candy bars were made of peanut butter crisp coated in a thin layer of chocolate, but nine years after the launch, the formula was modified to include chocolate, caramel and peanut-flavored crisps.

The yet-to-be-named bar will include chocolate, chocolatey crisps and peanut butter, according to a photo on whatchamacallitcontest.com.

Fans can visit the site and submit their name suggestions through June 15. Entrants may also share their name suggestions on Twitter and Instagram by tagging @watchamacallit and using #watchamacallit and #contest.

Judges will review submissions between June 16 and June 26. They will score each submission according to three weighted criteria: 1. “Relevance to the Brand”: 34 percent; 2. “Creativity”: 33 percent; and 3. “Originality”: 33 percent.

The winner will be notified on or around June 29.
