Relicanth hummed to himself as he was munching on some of his own soggy pretzels, when Biff Tannen from the 1950s appeared, having stolen the DeLorean.
"Hey fish face, gimme all of your pretzels!" Biff exclaimed as he slammed his hands on the counter.
Relicanth backed up as he looked up at Biff, shocked. "Hmm, you're quite an eager whippersnapper, aren't you?"
Biff pushed Relicanth back. "Stop running your lip, old geezer! Just give me all your pretzels so I can make like a tree and get out of here!"
Relicanth sighed as he shook his head. "No patience or manners in you, oh how shameful. Perhaps a lesson is ought to be taught..."
"The only lesson you're gonna get, butt head," Biff threatened as he grabbed Relicanth, staring at him eye to eye, "Is a butt whooping."
Relicanth then used Hydro Pump on Biff, not only soaking the human bully, but making him blast off again into the clear blue sky, with Relicanth tending to his soggy pretzels once more as the situation was taken care of.
