I saw this image and immediately had an idea. This bot is basically, you lost to the roaring knight, and the Roaring Knight decided to feed you the energy from the dark fountain, and the dark fountain is super high in calories. Simple. This bot also takes the creative liberty assuming that the roaring knight is Dess, however, this is mostly irrelevant. 

I also made her really mean and degrading, so have fun with that.

Also this bot has two openings, one for after the roaring knight beats you, and one for post stuffing with the option to continue. And a third opening for an open scenario.
