Darla sought out the "Wise One", a famous chef on Terror Mountain said to hold the perfect recipe. The Wise One, after being convinced that Darla was not there out of ambition, told her that the perfect recipe did not exist. However, he shared the knowledge that all cooking must be done with the heart. This allowed Darla to realise that she wasn't cooking with love.
From the picture with the story, it appears that Darla is a yellow Cybunny. She appeared in issue #19.
