It looked like a formless lump, wobbling in front Biff like an alien dessert. It was like a jelly he might have served in the cafeteria, but with a high-tech core which pulsed lights and emitted a dull mechanical throb. It even felt gelatinous when Biff picked it up; firm enough to stay together, but slimy enough that he worried it might slip from his grasp.
There seemed to be no buttons, levers, dials, switches, handles, or triggers. But the lights, and sounds, the sense of it, said ‘machine’ to Biff. Seven lights pulsed at regular intervals through the goo, like a secret code, each one coinciding with a barely audible tone.
He looked at it closely, trying to keep a grip as he turned it around in his hands. It felt weird and he didn’t understand it at all, but Biff was fascinated. It was strange. It was alien. It was the coolest thing he’d ever seen.
Then it made a noise at him. A distinct set of bleeps and boops, like it was starting a conversation, almost childish sounding, but with textures and layers in the sound that were as strange as distant stars.
